soc/intel/jasperlake: Enable wake from USB

Use the common UWES ACPI method to enable wake from USB. The only
difference to other SoCs is that JSL only has 8 USB2 ports, so the USB3
PORTSC register offset is different.

BUG=b:300844110
TEST=When enabled on taranza, all USB2 and USB3 ports can wake from
suspend
