ARM: SoC driver updates

Browse source 
Driver updates for ARM SoCs.
 
 A handful of driver changes this time around. The larger changes are:
 
  - Reset drivers for hi3660 and zx2967
  - AHCI driver for Davinci, acked by Tejun and brought in here due to
    platform dependencies
  - Cleanups of atmel-ebi (External Bus Interface)
  - Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
    register range on the SoCs)
  - PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)
