A few notable changes:
- Microcode init is done in assembly during the CAR init.
- The DCACHE_BSP_STACK_SIZE is set to 0x2000, which is the same size
against which the romstage stack guards protected.
- The romstage mainboard_lpc_init() hook is removed in favor of the
existing bootblock_mainboard_early_init().

This allows to read and set bits in the EC ram in the bootblock or
verstage. This can be useful if one needs to read a keyboard key as an
input for get_recovery_mode_switch in vboot.

The NO_POST option covers more than classical port 80 output, hence
selecting it seems wrong in any case. The default is still rather
user patronizing, but let's keep it.
As a side effect, this fixes the ability to override the default
for NO_POST which Kconfig rejected while these boards selected it.
(Seems like a bug in Kconfig, though.)

Load the calibration params from flash first and check the correctness
of the params. If the params have correct format, perform DRAM fast
calibration with these params to reduce bootup time. Otherwise, load the
DRAM blob and perform DRAM full calibration.
