soc/intel: Move USB wake methods to a common ASL file
The ACPI methods for enabling USB wake are identical on ADL, CNL and
SKL. Move them to a common ASL file so they can be reused more easily
on other SoCs.
Also move the USB_PORT_WAKE_ENABLE macro used to create enable bitmasks
in devicetree to a common header.
BUG=b:300844110
TEST=Use abuild to build kinox, puff, and fizz with and without this
change. Check the generated dsdt.aml is unchanged.
