Most OMAP3-based boards use exactly the same code for .map_io method in
the machine_desc structure.
This patch introduces omap3_map_io and updates board-* files to use it
as .map_io method.

The only difference between them is the physical address of the
uart4 port, which is only present in 36xx chips.

We don't really need to care about keeping these 2 functions, since
the decision to use uart4 is more cleanly done later when we do have
access to omap_revision variable.

Commit 48feb337 arm: omap: switch over to gpio_set_debounce caused
"undefined reference to omap_set_gpio_debounce" build error.

The fix is to use the generic gpiolib function.
