soc/intel/quark: Add C bootblock

Add a bootblock which builds with C_ENVIRONMENT_BOOTBLOCK selected.
This is the first piece in supporting FSP 2.0.  Move esraminit from
romstage into the bootblock.  Replace cache_as_ram with
car_stage_entry.S and code in romstage.c

TEST=Build and run on Galileo Gen2
