mainboard/google/reef: update DMIC related pins configuration 

CLK_B1(GPIO_80) and DATA_2(GPIO_83) pins needs to be
configured as native mode to use them for DMIC record
on other potential DMIC's.

DMIC blobs configure the clocks. For stereo & quad channel
record, both CLK_A1 and CLK_B1 are enabled.
For mono channel record, only CLK_A1 is enabled.

BUG=chrome-os-partner:56918
BRANCH=None
TEST=During DMIC record, check CLK_B1 and DATA_2 lines
