mb/google/volteer: Fix camera dsdt config for ov2740
Link frequency and a format was not correct for volteer proto 2
ov2740 user-facing camera.
The link frequency is calculated in the following way.
(max frame width * max frame height * max fps * data format in bps
/ number of lanes / data rate) + max 35% of overhead
For ov2740, (1920 * 1080 * 60 * 10 / 2 / 2) = 311Mhz.
360Mhz after adding 18% of overhead.
BUG=b:148428976
BRANCH=none
TEST=Build and boot volteer proto 2 board. Start a camera app
and check user-facing camera functionalities.
