Hermes Wu 041d61ad66 drm/bridge: it6505: add I2C functionality on AUX 
DisplayPort AUX protocol supports I2C transport which is capable of
reading EDID or supports MCCS.

In drm_dp_helper, drm_dp_i2c_xfer() packs I2C requests into a
sequence of AUX requests.
it6505_aux_i2c_operation() is implemented to match drm_dp_i2c_xfer()
operactions.
it6505_aux_i2c_transfer() adds I2C functionality
for it6505_aux_transfer().
