drm/i915/adl_s: Add adl-s ddc pin mapping

ADL-S requires TC pins to set up ddc for Combo PHY B, C, D and E.
Combo PHY A still uses the old ddc pin mapping.

From VBT, ddc pin info suggests the following mapping:
VBT 			               DRIVER
DDI B->ddc_pin=2 should translate to PORT_D->0x9
DDI C->ddc_pin=3 should translate to PORT_E->0xa
DDI D->ddc_pin=4 should translate to PORT_F->0xb
DDI E->ddc_pin=5 should translate to PORT_G->0xc

Adding pin map to facilitate this translation as we cannot use existing
icl ddc pin map due to conflict with DDI B and DDI C info.

Bspec:20124

v2: Replace IS_ALDERLAKE_S() with HAS_PCH_ADP() as the pin map pairing
depends on the PCH being used rather than the platform.(mdroper)

v3:
- Modify adls_port_to_ddc_pin() to make PHY_A the special case for
  check, else return pin mapping based on correct arithmetic with phy
  offset. Remove redundant platform checks and use HAS_PCH_ADP() instead
  of IS_ALDERLAKE_S() in intel_hdmi_ddc_pin().(mdroper)
