 - Remove old kernel version compat code
 - Make some functions static
 - Move to irq chip bus lock
 - Fix broken irq handler registration
 - Fix interrupt count
 - Use direct interrupt instead of via unimplemented PRCMU
 - Add RTC interrupts
 - Fix RTC register list
 - Allow get_page to read more than 4 registers
