soc/intel/cannonlake: Disable RTC write protect

The cannonlake FSP enables PchLockDownRtcMemoryLock by default, but we
need this memory to be writable.  We normally over-ride this in the
SoC chip init code, so we'll do the same on cannonlake.

BUG=b:71722386
BRANCH=none
TEST=Filled /dev/nvram with 0xff and 0x00 bytes to verify we can flip
all the bits.
