be a choice of a specific board.

This is architecture-dependent early initialization hence should
be put in the platform Kconfig.

3612b1efeb x86: kconfig: Select ARCH_MISC_INIT in the platform Kconfig
arch_misc_init() is intended to do architecture-dependent stuff.
This is required by each platform.

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.

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.

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.
