x86: slimbootloader: Set TSC information for tsc_timer
Slim Bootloader already calibrated TSC and provides it to U-Boot.
Therefore, U-Boot does not have to re-calibrate TSC.
Configuring tsc_base and clock_rate makes x86 tsc_timer driver bypass
TSC calibration and use the provided TSC frequency.
- Get TSC frequency from performance info hob
- Set tsc_base and clock_rate for tsc_timer driver
