drm/i915/icl: Map VBT DDC Pin to BSpec DDC Pin
On ICL we need to map VBT DDC Pin to BSpec DDC Pin.
Adding ICL Pin Values.
According to VBT
Block 2 (General Bytes Definition)
DDC Bus
+----------+-----------+--------------------+
| DDI Type | VBT Value | BSpec Mapped Value |
+----------+-----------+--------------------+
| DDI-A | 0x1 | 0x1 |
| DDI-B | 0x2 | 0x2 |
| PORT-1 | 0x4 | 0x9 |
| PORT-2 | 0x5 | 0xA |
| PORT-3 | 0x6 | 0xB |
| PORT-4 | 0x7 | 0xC |
