drm/bridge: analogix_dp: handle AUX transfer timeouts

Browse source

Timeouts on the AUX bus are to be expected in certain normal operating
conditions. There is no need to raise an error log or re-initialize the
whole AUX state machine. Simply acknowledge the AUX_ERR interrupt and
let upper layers know about the timeout.
