[ARM] Clean up save_and_disable_irqs macro and allow use of ARMv6 CPSID
save_and_disable_irqs does not need to use mov + msr (which was introduced to work around a documentation bug which was propagated into binutils.) Use msr with an immediate constant, and if we're building for ARMv6 or later, use the new CPSID instruction. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
