ALSA: hda/realtek - Simplify alc885_fixup_macpro_gpio()
The fixup for Macbook Pro is nothing but setting the GPIO bits as usual but with one exception: it adds some delay at writing the GPIO bits. Add a flag to put the conditional delay in the common helper, and clean up alc885_fixup_macpro_gpio() with the new flag. Signed-off-by: Takashi Iwai <tiwai@suse.de>
