From: Jyotheeswar Reddy Mutthareddyvari <jyothee@xhdsivadur40>
Currently DP power domain (pd_dp) is not attached to any of the DP nodes which
is
causing genpd to trigger a power down request for DP domain, making all DP
related
peripherals unusable. So assign power domains for all DP related nodes to enable
proper accounting of DP power domain usage.
