Picasso's FCH has many similarities to Stoney Ridge, so few changes
are necessary. The most notable changes are:
* Update the index values for the C00/C01 interrupt routing
* FORCE_STPCLK_RETRY is not present
* PCIB is not defined
* FCH MISC Registers 0xfed80e00 numbering has changed
* C-state base moves from PM register to MSR
* Add option to determine the intended MUX settion for LPC vs. eMMC
* Remove the LEGACY_FREE option
