There's no need to manually have to set the module owner of a class, the
compiler should do it automatically for you, so add a module * to the
__class_register() function and allow it to set the module owner
automatically.
This will let us move the module pointer out of struct class eventually,
as it should not be embedded in there if we wish for it to be a
read-only structure eventually.
And, funny story, this module pointer isn't even being used for
anything, so while we will keep it around for now, it's not like it even
matters.

Without an explicit level the stacktraces are printed at a default
level.
If this level does not match the one from the logging level it may
happen that the stacktrace is shown without the message or vice versa.
Both these cases are confusing, so make sure the user always sees both,
the message and the stacktrace.

The arbitration of the UART DMA is mishandled for a few
exceptional cases when probing and releasing the driver.
It is possible that the DMA register spaces are not defined in
device tree for an instance of the driver, so attempts to access
the registers in brcmuart_arbitration() would use NULL pointers.
It is also possible for the probe function to return an error
while still holding the UART DMA. This would prevent the UART
DMA from being claimed by an instance that could use it.
These errors are addressed by only releasing the UART DMA if it
is held by this instance (i.e. priv->dma_enabled == 1) and
directing early error paths in probe to this common release_dma
handling.

Backend DAIs may support multiple audio formats. Modify pipeline
setup to select a suitable configuration based on topology and
frontend DAI runtime configuration.
For sampling rate, if one of the BE DAI configurations has
a sampling rate matching that of FE DAI, configure BE DAI to
this rate.
For sample format, the current code hardcodes DAI copier sample format
to 32bit for both playback and capture pipelines. This is not always
desired, so lift the limitation and set the sample format based on
topology definitions for the copiers. For capture pipelines, we want to
set the BE DAI pipeline format based on topology instead of using the FE
DAI format. This covers the common use-case where BE DAI outputs data at
a higher sample precision and sample width is reduced later in the
pipeline. Instead of hardcoding to 32bit, use the BE DAI copier output
format defined in topology.

- frame timestamp (last start of vblank) (g4x+), already had this defined
- flip timestamp (when SURF was last written) (g4x+)
- flipdone timestamp (when last flipdone was signalled) (tgl+)
Note that on pre-tgl the flip related timestamps are only updated
for primary plane flips, but on tgl+ we can select which plane
updates them (via PIPE_MISC2). Let's define those related bits
as well.
Curiously VLV/CHV do not have the frame/flip timestamp registers,
despite all the other related registers being inherited from g4x.
This means we can get rid of the pipe_offsets[] usage for these,
and thus the implicit dev_priv is gone as well.

All functions referenced via __PV_IS_CALLEE_SAVE() need to be assembler
functions, as those functions calls are hidden from the compiler.
In case the kernel is compiled with "-fzero-call-used-regs" the compiler
will clobber caller-saved registers at the end of C functions, which
will result in unexpectedly zeroed registers at the call site of the
related paravirt functions.
Replace the C functions with DEFINE_PARAVIRT_ASM() constructs using
the same instructions as the related paravirt calls in the
PVOP_ALT_[V]CALLEE*() macros. And since they're not C functions visible
to the compiler anymore, latter won't do the callee-clobbered zeroing
invoked by -fzero-call-used-regs and thus won't corrupt registers.
