Now that the critical read back to flush the next descriptor address is
fixed we can downgrade some BUG_ONs that need only be enabled when testing

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.
