soc/intel/cannonlake: Assign FSP UPDs for HPD and Data/CLK of DDI ports

Assign the FSP UPDs for HPD and DDC of DDI ports. FSP assumes that all
DDI ports are enabled and hence configures the HPD and CLK for DDI ports.
This patch initializes only the required UPDs to enable display ports.

BUG=b:123907904
TEST=DP devices working correctly.
