drm/i915/mtl: Add MTP ddc pin configuration

Browse source 
Meteorlake PCH reuses Alderlake vbt, DE pin mapping. Extend
ADL-P pin mapping for Meteorlake.

Bspec: 20124 does not have the mapping for MTP. Based on Bspec:49306, 64051,
it is concluded that MTP and ADL-P PCH have the same vbt -> DE pin pair mapping.
