ARM: sa1111: add platform enable/disable functions
Add platform hooks to be called when individual sa1111 devices are enabled and disabled. This will allow us to move some platform specifics out of the individual drivers. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
