Currently, when attaching a domain to a device or its PASID, domain is
stored within the iommu group. It could be retrieved for use during the
window between attachment and detachment.
With new features introduced, there's a need to store more information
than just a domain pointer. This information essentially represents the
association between a domain and a device. For example, the SVA code
already has a custom struct iommu_sva which represents a bond between
sva domain and a PASID of a device. Looking forward, the IOMMUFD needs
a place to store the iommufd_device pointer in the core, so that the
device object ID could be quickly retrieved in the critical fault handling
path.
Introduce domain attachment handle that explicitly represents the
attachment relationship between a domain and a device or its PASID.

Currently the TBU driver will only probe when CONFIG_ARM_SMMU_QCOM_DEBUG
is enabled. The driver not probing would prevent the platform to reach
sync_state and the system will remain in sub-optimal power consumption
mode while waiting for all consumer drivers to probe. To address this,
let's register the TBU driver in qcom_smmu_impl_init(), so that it can
probe, but still enable its functionality only when the debug option in
Kconfig is enabled.

When KFENCE is enabled, total system memory is mapped at page level
granularity. But in radix MMU mode, ~3GB additional memory is needed
to map 100GB of system memory at page level granularity when compared
to using 2MB direct mapping.This is not desired considering KFENCE is
designed to be enabled in production kernels [1].
Mapping only the memory allocated for KFENCE pool at page granularity is
sufficient to enable KFENCE support. So, allocate __kfence_pool during
bootup and map it at page granularity instead of mapping all system
memory at page granularity.
Without patch:
# cat /proc/meminfo

With patch:
# cat /proc/meminfo

Note that enabling KFENCE at runtime is disabled for radix MMU for now,
as it depends on the ability to split page table mappings and such APIs
are not currently implemented for radix MMU.

The current fsl_qmc_audio works in interleaved mode. The audio samples
are interleaved and all data are sent to (received from) one QMC
channel.
Using several QMC channels, non interleaved mode can be easily
supported. In that case, data related to ch0 are sent to (received from)
the first QMC channel, data related to ch1 use the next QMC channel and
so on up to the last channel.
In terms of constraints and settings, the two modes are slightly
different:
- Interleaved mode:
- The sample size should fit in the number of time-slots available
for the QMC channel.
- The number of audio channels should fit in the number of
time-slots (taking into account the sample size) available for the
QMC channel.
- Non-interleaved mode:
- The number of audio channels is the number of available QMC
channels.
- Each QMC channel should have the same number of time-slots.
- The sample size equals the number of time-slots of one QMC
channel.
Add support for the non-interleaved mode allowing multiple QMC channel
per DAI. The DAI switches in non-interleaved mode when more that one QMC
channel is available.

The current QMC audio driver uses only one QMC channel per DAI. The
context used by QMC channel transfer (read and write) completion
routines does not contains any QMC channel and the only one available
per DAI is used to schedule the next transfer.
This works pretty well with only one QMC channel per DAI.
The future support for non-inlerleave mode will use several QMC channel
per DAI. In that case, QMC channel transfer completion routines need to
identify the QMC channel related to the completion.
In order to fill this lack, even if identifying the current QMC channel
among several QMC channels is not needed for the current code, add one
indirection level and introduce the qmc_dai_chan data structrure.
This structure contains the QMC channel involved in the completion and
refererences to the runtime context (capture and playback) used by the
DAI.

The driver mixes some internal values for channel DMA buffer handling
and PCM pointer handling. In the currently supported interleaved mode,
this mix does not lead to any issues but in order to prepare the
support for the non-interleaved mode, having them clearly separated will
ease the support and avoid additional computation to convert values used
in channel DMA buffer management in values usable for PCM pointer.
Use a specific set of variable for PCM pointer handling and an other set
for channel DMA buffer.

./scripts/checkpatch.pl --strict --codespell detected several issues
when running on the fsl_qmc_audio.c file:
- CHECK: spaces preferred around that '*' (ctx:VxV)
- CHECK: Alignment should match open parenthesis
- CHECK: Comparison to NULL could be written "!prtd"
- CHECK: spaces preferred around that '/' (ctx:VxV)
- CHECK: Lines should not end with a '('
- CHECK: Please don't use multiple blank lines
Some of them are present several times.
Fix all of these issues without any functional changes.

This replaces custom macros usage (i.e ID_AA64PFR0_EL1_ELx_64BIT_ONLY and
ID_AA64PFR0_EL1_ELx_32BIT_64BIT) and instead directly uses register fields
from ID_AA64PFR0_EL1 sysreg definition. Finally let's drop off both these
custom macros as they are now redundant.
