Russell King fc611a1a50 [ARM] Don't include mach-types.h unnecessarily
It's pointless to include mach-types.h if you're not going to use
anything from it.  These references were removed as a result of:

grep -lr 'asm/mach-types\.h' . | xargs grep -L 'machine_is_\|MACH_TYPE_\|MACHINE_START\|machine_type'
