[Animesh Manna]

HBR3 support for display gen11+ platform is depends upon some
conditions which are mentioned below.

ICL:
- eDP (only on DDI-A): Up to HBR3 for higher Vccio.
- DP:
        - (DDI-B, combo phy): upto HBR2.
        - (DDI-C to DDI-F): upto HBR3
 
RKLC:
- eDP/DP: Up to HBR3? Vccio dependent? (missing bspec pages)
 
JSL/EHL:
- eDP (DDI-A): Up to HBR2.
- DP (DDI-B to DDI-D): Up to HBR3 for higher Vccio _and_ retimers.
 
TGL:
- eDP (DDI-A to DDI-C): Up to HBR3 for higher Vccio.
- DP:
        - (DDI-A to DDI-C, combo phy): Up to HBR2.
        - (DDI-TC1 to DDI-TC6): Up to HBR3
 
DG1/ADL_S:
- eDP (all DDI is part of combo phy): Up to HBR3 for higher Vccio.
- DP (all DDI is part of combo phy): Up to HBR3 for higher Vccio _and_ retimers.
 
ADL_P/D13:
- eDP (DDI-A to DDI-B): Up to HBR3 for higher Vccio.
- DP:
        - (DDI-A to DDI-E): Up to HBR3 for higher Vccio.
        - (DDI-TC1 to DDI-TC4): Up to HBR3 for higher Vccio.
