[ARM] move include/asm-arm to arch/arm/include/asm
Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

- * The domain numbering depends on whether we support 36 physical

- * only be mapped using supersections and supersections can only
- * be set for domain 0. We could just default to DOMAIN_IO as zero,
