mb/google/volteer: Fix world-facing camera LED is always on issue
Volteer world-facing camera has a privacy LED and it is supposed
to be turned on only when the camera is being used. But the LED
is always on and this is to fix the issue.
RCAM_SNR_PWR_EN (RearCAMera_SeNsoR_PoWeR_ENable) GPIO, which
controls the world-facing camera LED, was not in the power-up
and power-down sequence definitions and this caused the issue.
BUG=b:160341981
BRANCH=none
TEST=Build and boot volteer proto 2 board. Start a camera app
and check the world-facing camera LED is only turned on only when
the camera is working.
