[PATCH] mtd/maps: gpio-addr-flash: Fix up the GENERIC_GPIO=n build.

[PATCH] mtd/maps: gpio-addr-flash: Fix up the GENERIC_GPIO=n build.

[Paul Mundt]

linux/gpio.h takes care of wrapping in to asm/gpio.h or defining a stubbed out
interface. gpio-addr-flush unfortunately references asm/gpio.h directly and as
a result blows up when CONFIG_GENERIC_GPIO is disabled.

I've opted to just switch to the linux/ version instead of adding a depends on,
as the driver still builds and does the error handling properly.
