drm/i915/dp: Initialize the link parameters during HW readout
Initialize the DP link parameters during HW readout. These need to be
up-to-date at least for the MST topology probing, which depends on the
link rate and lane count programmed in DPCD. A follow-up patch will
program the DPCD values to reflect the maximum link parameters before
the first MST topology probing, but should do so only if the link is
disabled (link_trained==false).
