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.
