mainboard/google/reef: Add proper DMIC endpoints based on DMIC config pin
Reef board uses GPIO_17 as DMIC config pin.
This pin distinguishes board with Quad DMIC's or Mono DMIC.
This patch adds necessary DMIC endpoints to support either of
those configurations.
CQ-DEPEND=CL:*304339,CL:409774
BUG=chrome-os-partner:56918
BRANCH=none
TEST=Verify Mono and Quad Channel DMIC record
