soc/intel/cannonlake: Disable USB2 PHY Power gating
Workaround to disable USB2 PHY power gating to fix issue seen when
Apple 87W USB-C charger is connected in S0ix state on WHL platforms
(based on Intel's recommendation). Issue is seen on CML platforms also.
So, disable power gating for Drallion too.
Add devicetree entry to set the flag to disable USB2 PHY power gating
for different CNL PCH based platforms
BUG=b:133775942
TEST=Connect Apple 87W USB-C charger when the system is in sleep and check if
the system wakes up after that
