Store computed values of chroma and motion vectors offset because
they depends on width and height values which change if the resolution
change.

Since vb2 queue can store more than VB2_MAX_FRAME buffers, the
postprocessor buffer storage must be capable to store more buffers too.
Change static dec_q array to allocated array to be capable to store
up to queue 'max_num_buffers'.
Keep allocating queue 'num_buffers' at queue setup time but also allows
to allocate postprocessors buffers on the fly.

The register abstraction has wrappers around both the normal writel()
and its writel_relaxed() counterpart, but this has led to a lot of users
ending up with the relaxed version.
There is sometimes a need to intentionally pick the relaxed accessor for
performance critical functions, but I noticed that each hantro_reg_write()
call also contains a non-relaxed readl(), which is typically much more
expensive than a writel, so there is little benefit here but an added
risk of missing a serialization against DMA.
To make this behave like other interfaces, use the normal accessor by
default and only provide the relaxed version as an alternative for
performance critical code. hantro_postproc.c is the only place that
used both the relaxed and normal writel, but this does not seem
cricital either, so change it all to the normal ones.

In some configurations, gcc decides not to inline the register accessor
functions, which in turn leads to lots of temporary hantro_reg structures
on the stack that cannot be eliminated because they escape into an
uninlined function:
drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Mark all of these as __always_inline so the compiler is able to completely
eliminate the temporary structures instead, which brings the stack usage
back down to just the normal local variables.

AV1 film grain feature requires to use the postprocessor to produce
valid frames. In such case the driver shouldn't propose native pixels
format but only post-processed pixels format.
Additionally if when setting a control a value could change capture
queue pixels formats it is needed to call hantro_reset_raw_fmt().

AV1 hardware decoder needs entropy parameters to decode frames.
They are computed from various arrays defined in AV1 section
"9.4. Default CDF tables".
Add helpers functions to init, store and get these parameters.

The Hantro mainline driver has been used in production
since several years and was only kept as a staging driver
due the stateless CODEC controls.
Now that all the stateless CODEC controls have been moved
out of staging, graduate the driver as well.
