Get rid of the old romstage-as-bootblock ROM layout
This change removes CONFIG_TINY_BOOTBLOCK, CONFIG_BIG_BOOTBLOCK, and all their uses, assuming TINY_BOOTBLOCK=y, BIG_BOOTBLOCK=n. This might break a couple of boards on runtime, but so far, fixes were quite simple. There's a flag day: Code that relies on CONFIG_TINY_BOOTBLOCK must be adapted.
