drm/i915: Explicitly map broxton DPIO power wells to phys

Browse Source 
The mapping from the BXT_DPIO_CMN_* power wells to their respective phys
required a detour implemented in the bxt_power_well_to_phy() function.
Instead, embed that information directly into the power_well struct, by
resurrecting the data field.
