ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5
The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs.
These SoCs have different gpio count but currently omap_gpio driver uses hard
coded 192 which is wrong.
This patch fixes this issue by:
1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h.
2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5.
Thanks for Lubomir Popov to provide valuable comments to fix this issue.
