This patch adds the probing of HCCS driver, and obtains all HCCS port

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset first fixes a number of errors made in the hda-mlink
support, then adds Lunar Lake definitions. The main contribution is
the hda-dai changes where the HDaudio DMA is now used for SSP, DMIC
and SoundWire. In previous hardware the GPDMA (aka DesignWare) was
used and controlled by the audio firmware. The volume of code is
minimized with the abstraction added in previous kernel cycles.
Due to cross-dependencies between ASoC and SoundWire trees, the full
support for jack detection will be deferred to the next kernel
cycle. There's not much point to ask for a sync of the two trees to
support one patch for each tree - we are at -rc5 already.

zicbom_block_size and zicboz_block_size have a peculiar API: they can be
read via get_one_reg() but any write will return a EOPNOTSUPP.
It makes sense to return a 'not supported' error since both values can't
be changed, but as far as userspace goes they're regs that are throwing
the same EOPNOTSUPP error even if they were read beforehand via
get_one_reg(), even if the same read value is being written back.
EOPNOTSUPP is also returned even if ZICBOM/ZICBOZ aren't enabled in the
host.
Change both to work more like their counterparts in get_one_reg() and
return -ENOENT if their respective extensions aren't available. After
that, check if the userspace is written a valid value (i.e. the host
value). Throw an -EINVAL if that's not case, let it slide otherwise.
This allows both regs to be read/written by userspace in a 'lazy'
manner, as long as the userspace doesn't change the reg vals.

get_one_reg() and set_one_reg() are returning EINVAL errors for almost
everything: if a reg doesn't exist, if a reg ID is malformatted, if the
associated CPU extension that implements the reg isn't present in the
host, and for set_one_reg() if the value being written is invalid.
This isn't wrong according to the existing KVM API docs (EINVAL can be
used when there's no such register) but adding more ENOENT instances
will make easier for userspace to understand what went wrong.
Existing userspaces can be affected by this error code change. We
checked a few. As of current upstream code, crosvm doesn't check for any
particular errno code when using kvm_(get|set)_one_reg(). Neither does
QEMU. rust-vmm doesn't have kvm-riscv support yet. Thus we have a good
chance of changing these error codes now while the KVM RISC-V ecosystem
is still new, minimizing user impact.
Change all get_one_reg() and set_one_reg() implementations to return
-ENOENT at all "no such register" cases.

KVM userspaces need to be aware of the host SATP to allow them to
advertise it back to the guest OS.
Since this information is used to build the guest FDT we can't wait for
the SATP reg to be readable. We just need to read the SATP mode, thus
we can use the existing 'satp_mode' global that represents the SATP reg
with MODE set and both ASID and PPN cleared. E.g. for a 32 bit host
running with sv32 satp_mode is 0x80000000, for a 64 bit host running
sv57 satp_mode is 0xa000000000000000, and so on.
Add a new userspace virtual config register 'satp_mode' to allow
userspace to read the current SATP mode the host is using with
GET_ONE_REG API before spinning the vcpu.
'satp_mode' can't be changed via KVM, so SET_ONE_REG is allowed as long
as userspace writes the existing 'satp_mode'.
