gpio/omap: make gpio_context part of gpio_bank structure
Currently gpio_context array used to save gpio bank's context, is used only for OMAP3 architecture. Move gpio_context as part of gpio_bank structure so that it can be specific to each gpio bank and can be used for any OMAP architecture Signed-off-by: Charulatha V <charu@ti.com> Reviewed-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Reviewed-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
