mb/google/volteer: Separate power resource for VCM
The camera privacy LED blinks during the boot and this gives a wrong
impression to the users that the camera is being used during the power
up. The blink happens when the camera module is probed and a series of
kernel patches and coreboot patches are being submitted to resolve the
issue.
The kernel patches are submitted to the chromium gerrit.

This is to separate the power resource for the VCM so that it can be
controlled by the driver and suppress the LED turn on.
BUG=b:169049942
BRANCH=none
TEST=Build and boot volteer board. Monitor camera privacy LED
and check if it blinks. It should not blink.
