Prep work for DP branch device handling

This series of patches reads DPCD register 0x80h for receiver
capabilities for DP branch devices. The branch device types are
converters for the following standards

- DP to VGA
- DP to DVI
- DP to HDMI
- DP++ dual mode
- Wireless WiGig

DPCD register defines max pixel rate for VGA dongles. This
check is carried out during mode validation.

v2: DPCD register read outs moved to drm (Ville, Daniel)
v3: Max pixel rate computation moved to drm (Daniel)
v4: Use of drm_dp_helper routines to collect data (Ville)
v5: Remove duplicate code and unnecessary functions from drm_dp_helper (Ville)
v6: Rebase and i915_debugfs cleanup
v7: Structure cleanups and initial step to move DP debugging info to drm_dp_helpers

Mika Kahola (5):
drm: Read DP branch device HW revision
drm: Read DP branch device SW revision
drm/i915: Check pixel rate for DP to VGA dongle
drm: Update bits per component for display info
drm: Add DP branch device info on debugfs
