drm/i915/ehl: Define EHL powerwells independently of ICL



Outputs C and D on EHL are combo PHY outputs and thus should not be
using the same TC AUX power well handlers as ICL.  And even though
icl_combo_phy_aux_power_well_ops works okay for EHL/JSL combo PHYs none
of its special handling is actually necessary for this platform:
 * EHL/JSL don't actually need to program PORT_CL_DW12
 * Display WA #1178 does not apply to EHL/JSL

Thus we can simply drop back to using our standard "hsw-style" power
well ops for EHL AUX power wells.

Bspec: 4301
