[U-Boot] [PATCH v9 6/9] 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_ba
