Move CPU init closer to other SoC and CPX.
FSP-S only is aware of socket 0, thus all cores must rerun all
settings already done by FSP, in order to set up socket 1 as well.
FSP sets the following on socket0:
- Set BIT20 in MSR_VR_MISC_CONFIG
- Set LTR_IIO_DISABLE in MSR_POWER_CTL
Lock the following MSRs:
- MSR_SNC_CONFIG
- MSR_CONFIG_TDP_CONTROL
- MSR_FEATURE_CONFIG
- MSR_TURBO_ACTIVATION_RATIO
Also do the following as done on other SoCs:
- Configure VMX and lock it
- Enable LAPIC TPRs (fixes MWAIT support)
- Honor CONFIG_SET_MSR_AESNI_LOCK_BIT
- Set TCC thermal target as set in devicetree
Fixes 8 second wakeup time from LAPIC interrupts when in MWAIT.
TEST: Booted on ocp/tiogapass to Linux 6.9 with all cores in
ACPI C6, no boot delay or hung tasks could be found.
