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.
