ALSA: oxygen: Xonar DG(X): modify initialization functions
Change CS4245 initialization: different sequence and GPIO values, according to datasheets and reverse-engineering information. Change cleanup/resume/suspend functions, since they use initialization. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
