drm/display: dp: implement new access helpers
Existing DPCD access functions return an error code or the number of
bytes being read / write in case of partial access. However a lot of
drivers either (incorrectly) ignore partial access or mishandle error
codes. In other cases this results in a boilerplate code which compares
returned value with the size.
Implement new set of DPCD access helpers, which ignore partial access,
always return 0 or an error code.
