When a DP connector is forced on using using the video=<connector>:e
kernel command line, we bypass the calls to check if the port is
connected and also bypass the call to intel_dp_detect_dpcd(); The
result is that we don't query for the sink capabilities like the
max link bandwidth. The sink capabilities are needed to set a
mode.
The solution is to add a call to intel_dp_detect_dpcd() in the code
path for forced on DP connectors.

Unrelated: CPU pipe A FIFO underrun and test is not using DP ports.

> pass -> FAIL (snb-x220t)
Failure is on vga connector so unrelated to code change in DP code.
