This patch-set provides unified Atmel AIC (Advanced Interrupt Controller)
driver. Currently, there are two AIC drivers, AIC and AIC5.
Each driver consists of chip specific part (irq-atmel-aic.o or
irq-atmel-aic5.o) and shared code (irq-atmel-aic-common.o).
But consolidated AIC driver is just one file driver which supports both
IRQ chip systems.

How to handle two IRQ chips in one driver
-----------------------------------------
  Structure aic_reg_offset is used for device configuration.
  AIC5 IRQ chip uses SSR (Source Select Register) to select IRQ number.
  On the other hand, AIC IRQ chip has simple register access.
  To support both IRQ chips, aic_is_ssr_used() helper is used.

Patches
-------
  1 ~  5: fix IRQ priority issue, clean up RTC/RTT fixup code and etc.
  6 ~ 19: create unified IRQ chip operation with aic_reg_offset data.

Target boards
-------------
  Tested with two boards.
  * Arietta G25 (SoC: AT91SAM9G25)
  * Xplained board (SoC: SAMA5D3)

Number of driver files
----------------------
  AIC:              3 (irq-atmel-aic.c, irq-atmel-aic-common.c and h)
  AIC5:             3 (irq-atmel-aic5.c, irq-atmel-aic-common.c and h)
  Consolidated AIC: 1 (irq-aic.c)
