drm/i915/rkl: new rkl ddc map for different PCH
After boot into kernel. Driver configured ddc pin mapping based on
predefined table in parse_ddi_port(). Now driver configure rkl
ddc pin mapping depends on icp_ddc_pin_map[]. Then this table will
give incorrect gmbus port number to cause HDMI can't work.
Refer to commit cd0a89527d06 ("drm/i915/rkl: Add DDC pin mapping").
Create two ddc pin table for rkl TGP and CMP pch. Then HDMI can
works properly on rkl.
v2: update patch based on latest dinq branch.
v3: update ddc table for RKL+TGP sku.
RKL+CNP sku will load cnp_ddc_pin_map[] setting.
v4: modify the if/else judgment to avoid nesting.
v5: fix typo in v4.
