[U-Boot] [PATCH v6 1/2] x86: Add TSC-specific timer functions

Coreboot timestamp functions and Quark memory reference code use get_tbclk() to get TSC frequency. This will not work if another early timer is selected. Add tsc_rate_mhz() function and use it in the code that specifically needs to get TSC rate regardless of currently selected early timer.
