reef: Enable sensors for ARC++

Browse Source 
- Enable MKBP events:
Allow EC to send sensor event to the kernel sensor stack.
- Disable APCI message display, to avoid overwhelming the console.
- Set the rotation matrices to match Android requirement.

BUG=b:27849483
CQ-DEPEND=CL:384341
BRANCH=reef
TEST=Check we can receive sensor events for ARC++.
Check the acceleromter axis are correct.
