[PATCH 07/17] Input: omap-keypad: Remove dependencies to mach includes

[Tony Lindgren <tony@atomide.com>]

We can't build CONFIG_ARCH_OMAP1 set with ARCH_OMAP2PLUS because
of different compiler flags needed, so we can define omap_kp_24xx()
instead of using cpu_is_omap24xx(). This way we can remove
depency to plat and mach headers which is needed for ARM common
zImage support.

Also remove INT_KEYBOARD by using omap_kp->irq.

Note that this patch depends on an earlier patch
"ARM: OMAP: Move gpio.h to include/linux/platform_data".
