armv7: Prevent CBFS data overlapping bootblock.
For arm/snow, current bootblock is larger than previously assigned CBFS offset
and will fail to boot. To prevent this happening again in future, cbfstool now
checks if CBFS will overlap bootblock.
A sample error message:
E: Bootblock (0x0+0x71d4) overlap CBFS data (0x5000)
E: Failed to create build/coreboot.pre1.tmp.
arm/snow offset is also enlarged and moved to Kconfig variable.
