drm/i915/xe3p_lpd: Reload DMC MMIO for pipes C and D
Xe3p_LPD has the same behavior as for Xe3_LPD with respect to DMC
context data for pipes C and D, which are lost when their power wells
are disabled. As such, let's extend the condition for Xe3_LPD in
need_pipedmc_load_mmio() to also catch Xe3p_LPD.
