[ALSA] oxygen: separate out hardware initialization code
Create separate functions for the code that initializes the hardware, as opposed to initializing internal driver state, so that they can be reused for resume support. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
