    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.
    
    Finally, move some flags to the architecture Makefile, and
    rely on the fact that some are set for all architectures.
