Add support for system suspend/resume by moving the enable/disable
of interrupts in mchp_spdiftx_trigger() on SNDRV_PCM_TRIGGER_SUSPEND/
SNDRV_PCM_TRIGGER_RESUME commands.

Add runtime PM support for Microchip SPDIFTX driver. The runtime PM
APIs disables/enables IP's clock and enables/disable caching for
regmap.

Use a temporary variable to keep the AES3 value. With this a
spin_unlock_irqrestore() call has been removed from the final code.

A recent change in clang strengthened its -Wbitfield-constant-conversion
to warn when 1 is assigned to a 1-bit signed integer bitfield, as it can
only be 0 or -1, not 1:
sound/soc/atmel/mchp-spdiftx.c:505:20: error: implicit truncation from 'int' to bit-field changes value from 1 to -1 [-Werror,-Wbitfield-constant-conversion]
dev->gclk_enabled = 1;
^ ~
1 error generated.
The actual value of the field is never checked, just that it is not
zero, so there is not a real bug here. However, it is simple enough to
silence the warning by making the bitfield unsigned, which matches the
mchp-spdifrx driver.

Merge series from Claudiu Beznea <claudiu.beznea@microchip.com>:
Hi,
The series adds one fix for mchp-spdifrx and one cleanups for
mchp-spdifrx and mchp-spdifrx drivers.
Thank you,
Claudiu Beznea
Changes in v3:
- changed cover letter title s/few/one, s/cleanups/cleanup
- fix compilation error and warnings
- keep only patch 1/5 and patch 3/5 from previous version as the rest
of them were integrated
Changes in v2:
- s/tag/tab in the title of patch 2/5
Claudiu Beznea (2):
ASoC: mchp-spdifrx: disable end of block interrupt on failures
ASoC: mchp-spdiftx: remove references to mchp_i2s_caps

The series adds one fix for mchp-spdifrx and few cleanups for
mchp-spdifrx and mchp-spdifrx drivers.
Avoid having patterns like:
int ret;
// ...
ret = 0;
// ...
ret = call_function();
if (ret)
return ret;
return 0;
and return directly ret for all cases.

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.

The Validity bits (bit 28) must not be set in order to have the samples
valid. Some controllers look for this bit and ignore the samples if it
is set.

The new SPDIF TX controller is a serial port compliant with the IEC-
60958 standard. It also supports programmable User Data and Channel
Status fields.
This IP is embedded in Microchip's sama7g5 SoC.
