ASoC: atmel: mchp-spdiftx: Convert to platform remove callback returning void
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.

ASoC: mchp-spdiftx: update debug message
Previous debug message states that there was a failure and tx was not
disabled. Which is not true as the TX in this function could also be
enabled. Thus improve a bit the debug message by s/disable/start\/stop/.

ASoC: mchp-spdiftx: use regmap_update_bits()
Use regmap_update_bits() instead of regmap_read(), running variable,
regmap_write(). There is no need for extra variables and checks around
it as regmap_update_bits() already does this. With this code becomes
simpler.

ASoC: mchp-spdiftx: Fix clang -Wbitfield-constant-conversion
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.

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
