soc: mediatek: add SCPSYS power domain driver for MediaTek MT7622 SoC
Add SCPSYS power domain driver for MT7622 SoC having four power domains which are respectively ETHSYS for Ethernet including embedded switch, WBSYS for WIFI and Bluetooth, HIF0SYS for PCI-E and SATA, and HIF1SYS for USB. Those functions could be selectively powered gated when the corresponding function is no longer to use in order to reach more minimal power dissipation.
