Currently DP driver will allocate panel bridge for eDP panels.
Simplify this code to just check if there is any next bridge in the
chain (be it a panel bridge o
ge support for eDP panels. Change panel_bridge
attachment to come after dp_bridge attachment.

Current DP drivers have regulators, clocks, irq and phy are grouped
together within a function and executed not in a symmetric manner.
This increase difficulty of code maintenance and limited code

Some DP sinkers prefer to use tps4 instead of tps3 during training #2.
This patch will use tps4 to perform link training #2 if sinker's DPCD
supports it.
