x86/tsc: Use TSC as sched clock early
All prerequesites for enabling TSC as sched clock early in the boot
process are available now:
- Early attempt of TSC calibration
- Early availablity of static branch patching
If TSC frequency can be established in the early calibration, enable the
static key which switches sched clock to use TSC.
