Add support for the A/D 12-Bit successive approximation converters found
in the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs.
RZ/T2H has two ADCs with 4 channels and one with 6.
RZ/N2H has two ADCs with 4 channels and one with 15.
Conversions can be performed in single or continuous mode. Result of the
conversion is stored in a 16-bit data register corresponding to each
channel.
The conversions can be started by a software trigger, a synchronous
trigger (from MTU or from ELC) or an asynchronous external trigger (from
ADTRGn# pin).
Only single mode with software trigger is supported for now.

Change the allocation strategy of the 8 SETUP registers from a least-
recently-used (LRU) to a first-come-first-served basis.
The AD7124 chips can have up to 16 channels enabled at a time in the
sequencer for buffered reads, but only have 8 SETUP configurations
(namely the OFFSET, GAIN, CONFIG and FILTER registers) that must be
shared among the 16 channels. This means some of the channels must use
the exact same configuration parameters so that they can share a single
SETUP group of registers. The previous LRU strategy did not keep track
of how many different configurations were requested at the same time,
so if there were more than 8 different configurations requested, some
channels would end up using the incorrect configuration because the slot
assigned to them would also be assigned to a different configuration
that wrote over it later.
Adding such tracking to solve this would make an already complex
algorithm even more complex. Instead we can replace it with a simpler
first-come-first-serve strategy. This makes it easy to track how many
different configurations are being requested at the same time. This
comes at the expense of slightly longer setup times for buffered reads
since all setup registers must be written each time when a buffered read
is enabled. But this is generally not considered a hot path where
performance is critical, so should be acceptable.
This new strategy also makes hardware debugging easier since SETUPs are
now assigned in a deterministic manner and in a logical order.

The current error handling path in bnxt_re_destroy_gsi_sqp() could lead
to a resource leak. When bnxt_qplib_destroy_qp() fails, the function
jumps to the 'fail' label and returns immediately, skipping the call
to bnxt_qplib_free_qp_res().
Continue the resource teardown even if bnxt_qplib_destroy_qp() fails,
which aligns with the driver's general error handling strategy and
prevents the potential leak.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace

rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.

RK3528 ships a PCIe Gen2x1 controller that operates in RC mode only.
Since the SoC has no separate MSI controller, the one integrated in the
DWC PCIe IP must be used, and thus its interrupt scheme is similar to
variants found in RK3562 and RK3576.
Older BSP code claimed its integrated MSI controller supports only 8
MSIs[1], but this has been changed in newer BSP[2] and testing proves
the controller works correctly with more than 8 MSIs allocated,
suggesting the controller should be compatible with the RK3568 variant.
Hence, document its compatible string.
