Xiaopeng Bai 53e342c183 ANDROID: GKI: regmap: Add regmap vendor hook for of_syscon_register
For global registers access, UNISOC have one special method called set/clear
mechanism that would avoid using hardware spinlock. But now regmap framework
does not support our set/clear mechanism, so add vendor hook to support
this feature.
