soc/intel/common: Move support to log XHCI wake events
The policy to identify and log the XHCI wake events is similar between
skylake and apollolake. Hence move the similar parts to a common
location.
BUG=b:123429132
BRANCH=None
TEST=Ensure that the system boots to ChromeOS. Ensure that the wake up
events due to USB are logged into the event logs.
