The prev_sleep_state value was showing 5 even after warm reboot, once the
SUS_PWR_FLR bit is being set. This bit was not being cleared.
Hence clearing the PMCON status bits.
BUG=b:128482282
BRANCH=None
TEST=In cbmem logs, check for value of “prev_sleep_state” using command
cbmem –c | grep “prev_sleep_state”
For cold reboot, "prev_sleep_state 5"
For warm reboot, "prev_sleep_state 0"

In order to reduce BOM cost and board area for imaging solution, the
sensor requires a 19.2/24MHz reference clock from PCH. In addition to
that, having PCH to supply the sensor reference clock will prevent
dependency on CPU power management and also avoid level shifter cost.
Pch iSCLK is only required for CNP-LP with the camera sensor on the
platform.
BUG=None
TEST=Boot up into OS and read back PCH iSCLK programming through
iotools.
