update CFLAGS for armv7

This updates $CFLAGS used for armv7. Most of them were just added
    to be consistent with what u-boot does. The important ones here
    are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).

I removed the hard float support because it got errors and
    coreboot should never use floats anyway. We're still having trouble
    with enums but I want to see how far it gets with this patch.

Also, put the flags in a form that makes diffs easier to read. It's
    almost impossible otherwise.
