ASoC: Updates for v5.15

Quite a quiet release this time, mostly a combination of cleanups
and a good set of new drivers.

 - Lots of cleanups and improvements to the Intel drivers,
   including some new systems support.
 - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek
   Mt8195, Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P,
   Renesas RZ/G2L,, Rockchip RK3568 S/PDIF.

These have turned up some issues in further testing.

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.

For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.

This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by a spinlock.

As reboot_notify callback is no longer used by the codec core, let's
get rid of the unused code.  Conexant codec needs a slight code change
as it used to call the reboot_notify at the codec removal, too.

The recent refactoring of es1688 object creation with the use of
devres caused a problem with the non-PnP probe of GUS driver, as it
tries to probe multiple times with different parameters  That is, this
object needs the immediate resource release and the devres doesn't fit
for it.

This patch reverts partially the commit for restoring the classic
resource management for es1688 object.

Now with the recent addition of WC buffer allocation support, we can
use the standard PCM buffer allocation helpers for pxa2xx drivers.
This allows us to remove lots of superfluous code.

A few drivers want to have rather the exact buffer preallocation at
the driver probe time and keep using it for the whole operations
without allowing dynamic buffer allocation.  For satisfying the
demands, this patch extends the managed buffer allocation API
slightly.

Namely, when 0 is passed to max argument of the allocation helper
functions snd_pcm_set_managed_buffer*(), it treats as if the fixed
size allocation of the given size.  If the pre-allocation fails in
this mode, the function returns now -ENOMEM.  Otherwise, i.e. max
argument is non-zero, the function never returns -ENOMEM but tries to
fall back to the smaller chunks and allows the dynamic allocation
later -- which is still the default behavior until now.

For more intuitive use, also two new helpers are added for handling
the fixed size buffer allocation, too: snd_pcm_set_fixed_buffer() and
snd_pcm_set_fixed_buffer_all().

SNDRV_DMA_TYPE_DEV_UC and SNDRV_DMA_TYPE_DEV_UC_SG are incorrectly
named as if they were for the uncached memory, while actually we set
the pages as write-combined.  Rename them to reflect the right
attribute.
