drm/i915/adl_p: Add ddc pin mapping
From VBT, ddc pin info suggests the following mapping:
VBT DRIVER
DDI TC1->ddc_pin=3 should translate to PORT_TC1->0x9
DDI TC2->ddc_pin=4 should translate to PORT_TC2->0xa
DDI TC3->ddc_pin=5 should translate to PORT_TC3->0xb
DDI TC4->ddc_pin=6 should translate to PORT_TC4->0xc
Adding pin map to facilitate this translation as we cannot use existing
icl ddc pin map due to conflict with DDI C and DDI TC1 info.
