The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Microchip PDMC IP doesn't filter microphone noises on startup. By default,
it captures data received from digital microphones after
the MCHP_PDMC_MR.EN bits are set. Thus when enable is set on PDMC side the
digital microphones might not be ready yet and PDMC captures data from then
in this time. This data captured is poc noise. To avoid this the software
workaround is to the following:
1/ enable PDMC channel
2/ wait 150ms (on SAMA7G5-EK setup)
3/ execute 16 dummy reads from RHR
4/ clear interrupts
5/ enable interrupts
6/ enable DMA channel

Add support for suspend to RAM by re-aranging the lines in switch..case
from mchp_pdmc_trigger() and saving/restoring the enabled interrupts. These
are necessary as AT91 devices has a special power saving mode (called
backup and self-refresh) where most of the SoC parts are powered off
and thus we need to reconfigure the PDMC on resume.

Implement clock power saving taking advantage of runtime PM infrastructure.
This simplifies the code and allow using the same infrastructure for

Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
These drivers appear to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

In function mchp_pdmc_af_put(), Intel's kernel test robot reports the
following warning:
sound/soc/atmel/mchp-pdmc.c:186:34: warning: address of array \
'uvalue->value.integer.value' will always evaluate to 'true' \
[-Wpointer-bool-conversion]
This is because we are using `uvalue->value.integer.value` which its
type is `long value[128];` for conditional expression and that array
will always decay to a non-NULL pointer. Using a non-NULL pointer for
conditional expression will always evaluate to true.
Fix this by changing it to `uvalue->value.integer.value[0]` as that's
what the mchp_pdmc_af_get() function sets.

microphones having Pulse Density Modulated (PDM) outputs. It generates a
single clock line and samples 1 or 2 data lines. The signal path includes
an audio grade programmable decimation filter and outputs 24-bit audio
words on the APB bus.
