[ARM] 3847/2: Convert LOMOMO to use struct device for GPIOs
Convert LOMOMO to use struct device * for GPIOs instead of struct locomo_dev. This enables access to the GPIOs from code which is not a locomo device itself (such as audio). Access for gpio 31 is removed for error handling (no such hardware exists). Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
