skylake: ACPI: Clean up and fix XHCI ACPI Device

- Remove the old workarounds for XHCI from broadwell
- Add PMC device to expose bits needed for XHCI workarounds
- Implement the new workarounds for XHCI, the first will set
a bit in the XHCI MMIO and the second will send a message
to the PMC if a bit is set indicating the workaround is available.
- Clean up the HS/SS port defines and remove unnecessary
methods to determine the port count since we only support SPT-LP.

TEST=build and boot on glados, verify that D0 and D3 can be
made to work (by disabling unused USB and the misbehaving camera)
