Furquan Shaikh 3bfe3404df intel/skylake: Add support to enable wake-on-usb attach/detach 
Three things are required to enable wake-on-usb:
1. 5V to USB ports should be enabled in S3.
2. ASL file needs to have appropriate wake bit set.
3. XHCI controller should have the wake on attach/detach bit set for the
corresponding port in PORTSCN register.

Only part missing was #3.

This CL adds support to allow mainboard to define a bitmap in
devicetree corresponding to the ports that it wants to enable
wake-on-usb feature. Based on the bitmap, wake on attach/detach bits in
PORTSCN would be set by xhci.asl for the appropriate ports.

BUG=chrome-os-partner:58734
BRANCH=None
TEST=Verified that with port 5 enabled, chell wakes up from S3 on usb
attach/detach.
