Add ioremap() to map physical address to uncached virtual address. We need this to convert the reg address from the 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. tree
