cpu/intel/haswell: Use C_ENVIRONMENT_BOOTBLOCK
This puts the cache-as-ram init in the bootblock.
Before setting up cache as ram the microcode updates are applied.
This removes the possibility for a normal/fallback setup although
implementing this should be quite easy.
Tested on Google peppy (Acer C720).
Setting up LPC in the bootblock to output console on SuperIOs is not
done in this patch, hence BOOTBLOCK_CONSOLE is not yet enabled by
default.
