[PATCH 5/8] video: sa1100fb: use devm_gpio_request_one()

[rmk+kernel@armlinux.org.uk (Russell King)]

Switch to using devm_gpio_request_one() to request the shannon gpio
and move the request before the video memory allocation, so we request
all device managed resources before this large allocation attempt.
