ASoC: cs42l42: Fix missing include of gpio/consumer.h

The call to gpiod_set_value_cansleep() in cs42l42_sdw_update_status()
needs the header file gpio/consumer.h to be included.

This was introduced by commit 2d066c6a

 ("ASoC: cs42l42: Avoid stale
SoundWire ATTACH after hard reset")

and caused error:
    sound/soc/codecs/cs42l42-sdw.c:374:4: error: implicit declaration of
    function ‘gpiod_set_value_cansleep’;
    did you mean gpio_set_value_cansleep’?
