From: Sean Wang <sean.wang at mediatek.com>

Changes since v2:
- reduce code duplication of scpsys_probe across all SoCs

Changes since v1:
- rebase to Linux v4.13-rc1

There are four power domains on MediaTek MT7622 SoC which are respectively
ETHSYS for Ethernet including extra embedded switch, HIF0SYS for PCI-E and
SATA, HIF1SYS for USB and WBSYS for WIFI and Bluetooth.

Those functions could be selectively powered gated when the corresponding
function is no longer to use in order to reach more minimal power
dissipation through the patch series introduced here.
