soc/intel/cannonlake: Disable CpuRatio and SaGv in recovery
Disabling CpuRatio UPD for FSP will ensure it does not force a
hard reset to set the CPU Flex Ratio at boot. This is important
in a recovery mode boot where the SOC will lose power and need
to set the flex ratio again.
Disabling SaGv makes recovery mode training faster and mirrors
the setting that was done on Skylake.
BUG=b:123305400
TEST=reliably enter recovery mode on sarien
