Bin Meng 1d4c83c248 x86: tsc: Remove legacy timer codes 
Now that we have converted all x86 boards to use driver model timer,
remove these legacy timer codes in the tsc driver.

Note this also removes the TSC_CALIBRATION_BYPASS Kconfig option,
as it is not needed with driver model.

Bin Meng ea94532461 x86: quark: Bypass TSC calibration 
For some unknown reason, the TSC calibration via PIT does not work on
Quark. Enable bypassing TSC calibration and override TSC_FREQ_IN_MHZ
to 400 per Quark datasheet in the Kconfig.

Bin Meng 828d9af5ec x86: Add basic Intel Quark processor support 
Add minimum codes to support Intel Quark SoC. DRAM initialization
is not ready yet so a hardcoded gd->ram_size is assigned.
