drm/amd/display: Refactor reg_set and reg_update.

Browse Source 
[Why]
Current reg update and reg set use same functions and
only delta is update reads reg value and call update function.

[How]
Refactor reg update and reg set functions.
1.Implement different functions for reg update and reg set.
2.Wrap same process to a help function, both reg update and
reg set will call it.
