Subject: [PATCH v3 04/13] soc: rockchip: power-domain: Fix wrong value when power up pd

From: Finley Xiao <finley.xiao@...k-chips.com>

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:

	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.
