[Intel-gfx] [PATCH v6 1/2] drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.

This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the
