The ARMv8 zx2967 family (296718, 296716 etc) uses different value for controlling the power domain on/off registers, Choose the value depending on the compatible. Multiple domains are prepared for the family, this patch prepares the common functions. Signed-off-by: Baoyou Xie <baoyou.xie@linaro.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
