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.
