The two Type-C ports found on Glymur CRD are DisplayPort alternate mode
capable. Everything is in place already for the USB, but for DisplayPort
the controllers need to be enabled.

So enable the related DisplayPort controller for each of these two
ports. Also define the supported link frequencies for each output.

SoCCP support is still missing, so DP altmode won't work until SoCCP
support is added.
