Sampath Vangaveti dc89a99bdd QCamera2: HAL/HAL3: Convert Boottime from ISP to MONOTONIC 
Issue:
Diplay freeze observed sometimes, if there is any
suspend/resume of the device.
The issue found to be with differences in the timesources
used by display and camera for timestamp calculation.

Fix:
Measure the clock offset between BOOTTIME and MONOTONIC.
The clock domain source for ISP is BOOTTIME and
for display, it is MONOTONIC.
The offset is used to convert from clock domain of
camera to display.
Added following set prop to switch between camera time sources.

	persist.camera.time.monotonic <value>
Default value is 1.
value 0 indicates Boot time from camera.
value 1 indicates Monotonic time from camera.
