driver/i2c/max98927: Add imon and vmon params
This change list adds imon and vmon slot numbers as params for
Maxim 98927 driver. These values are looked up in the kernel driver
to confiure IV feedback for audio playback on speakers.
BUG=b:36724448
TEST=After boot, the register dump for Max98927 codecs should have
imon and vmon slots numbers set in 0x1e register.
