[ARM] Allow Versatile to be built for AB and PB
If a configuration was chosen to support both the Versatile AB and PB boards, the result would write to registers not available on the PB version of the board. Resolve this by using machine_is_xxx(). Also, for the CLCD, despite how the code looks, both the AB and PB access the same location to control the clock rate - it's just called something different between the two board versions. Invent our own name for this location and use it unconditionally. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
