[coreboot] Thinkpad H8 EC Registers

I'm trying to get the USB_ALWAYS_ON toggle between AC_ONLY and
AC_AND_BATTERY working, so I'm asking if anyone has any notes on the EC
registers (X220 specifically, but broader notes welcome). I've got some
diffs from the Lenovo BIOS but I can't identify the flag.
I think that the non-functional 0x0D flag in the original USB_ALWAYS_ON
patch gets fed straight to the charge controller, and that might explain
why it behaves a little weirdly.
Alternatively any other ideas are welcome too!
