arm64: zynqmp: PM: Specify power domains for DP related nodes

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.
