soc/intel/cannonlake: Add Pch iSCLK programming
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.
