From: Finley Xiao <finley.xiao@xxxxxxxxxxxxxx> Solve the pd could only ever turn off but never turn them on again, If the pd registers have the writemask bits. Fix up the code error for commit: commit 79bb17ce8edb3141339b5882e372d0ec7346217c Author: Elaine Zhang <zhangqing@xxxxxxxxxxxxxx> Date: Fri Dec 23 11:47:52 2016 +0800 soc: rockchip: power-domain: Support domain control in hiword-registers New Rockchips SoCs may have their power-domain control in registers using a writemask-based access scheme (upper 16bit being the write mask). So add a DOMAIN_M type and handle this case accordingly.
