Add ioremap() to map physical address to uncached virtual

device tree.

The order of headers inclusion in interrupts.c is changed
because common.h will include board header that contains
IO_REGION_BASE.

In the future, the IO_REGION_BASE should be decided from
the device tree.

Currently omap_hsmmc driver doesn't use sdcd pin to detect

With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be
parsed in xlate gpio drivers-ops. Since xlate is not implemented
in omap_gpio driver, the driver considers all gpio to be
ACTIVE_HIGH which is the default case and fails to return actual
gpio status for ACTIVE_LOW gpios. So adding .xlate ops to
omap_gpio.
