Currently we still go through DC code that does error checking, retries,
etc. There's no need for that since DRM already does that for us. This
simplifies the code a bit and makes it easier to debug.

This also ensures we correctly tell DRM how many bytes have actually
been read, as we should. This allows DRM to correctly read the EDID on
the Chamelium DP port.

DRM's DP helpers take care of dealing with the error code for us. In
order not to step on each other's toes we'll need to be able to simply
read auch channel replies without further logic based on return values.

Access to GPIO needs to be serialized. Aux transactions are already
serialized in DRM but we also need to serialize access to the GPIO pin
for purposes of DP dongle detection.

Call is_dp_sink_present through DM so we can lock correctly. This
follows the same pattern used for DPCD transactions.

 function description
 get/ set DP configuration: lane_count, link_rate, spread_spectrum

  valid lane count value: 1, 2, 4
  valid link rate value:
  06h = 1.62Gbps per lane
  0Ah = 2.7Gbps per lane
  0Ch = 3.24Gbps per lane
  14h = 5.4Gbps per lane
  1Eh = 8.1Gbps per lane

  debugfs is located at /sys/kernel/debug/dri/0/DP-x/link_settings

  --- to get dp configuration

  xxd -l 300 phy_settings

  It will list current, verified, reported, preferred dp configuration.
  current -- for current video mode
  verified --- maximum configuration which pass link training
  reported --- DP rx report caps (DPCD register offset 0, 1 2)
  preferred --- user force settings

  --- set (or force) dp configuration

  echo <lane_count>  <link_rate>

  for example, to force to  2 lane, 2.7GHz,
  echo 4 0xa > link_settings

  spread_spectrum could not be changed dynamically.

  in case invalid lane count, link rate are force, no hw programming will be
  done. please check link settings after force operation to see if HW get
  programming.

  xxd -l 300 link_settings

  check current and preferred settings.
