ARM: cache-v7: optimise test for Cortex A9 r0pX devices
Eliminate one unnecessary instruction from this test by pre-shifting the Cortex A9 ID - we can shift the actual ID in the teq instruction thereby losing the pX bit of the ID at no cost. Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
