snow: Stuff to support building image with BL1
This patch does two things which will take effect in follow-up
patches:
1. Add an intermediate Makefile rule for dd'ing BL1 into the
coreboot.rom pre-image. This is modeled after a similar hack
for the bd82x6x southbridge.
2. Add a Kconfig variable, BOOTBLOCK_OFFSET, which will be used to
pass the bootblock offset into cbfstool.
