ASoC: cs42l42: Split cs42l42_resume into two functions

Browse source

On SoundWire the system resume cannot restore registers until the
host controller has re-enumerated the peripheral.

This patch splits cs42l42_resume() into two functions, one to
power up and the other to restore registers, ready for adding
SoundWire support.
