sb/intel/ibexpeak: Add CIR initialization

This properly sets up the chipset initialization registers, instead of
replaying an RCBA dump.

The information is taken from the EDS and from the thinkpad x201
vendor BIOS disassembly and from an HP UEFI.

TESTED on Thinkpad X201. Seems stable at booting, rebooting and resume
from S3.
