drm/bridge: anx7625: Use common macros for DP power sequencing commands

Browse source 
[ Upstream commit 2ba776f903cb7157e80b5f314fb0b4faf6ea6958 ]

The DRM DP code has macros for the DP power sequencing commands. Use
them in the anx7625 driver instead of raw numbers.

Fixes: 548b512e14 ("drm/bridge: anx7625: send DPCD command to downstream")
Fixes: 27f26359de ("drm/bridge: anx7625: Set downstream sink into normal status")
