drm/i915/display: Extend DP HDR support to hsw+ 

HSW+ platforms are able to send out HDR Metadata SDP DIP
packet as GMP. Hence, extending the support for HDR on DP
encoders for the same.

v2: Limited to non eDP ports on hsw/bdw and removed it for
lspcon as it is done separately (suggested by Ville)

v3: Added helper and limited eDP restriction to port A (Ville)

v4: Dropped some redundant checks (Ville)
