disp: msm: encoder_ids replaced in drm_connector

Browse Source 
Commit 62afb4ad425a ("drm/connector: Allow max possible encoders
to attach to a connector") enables additional encoders per
connector through use of a mask rather than encoder ids.
This change updates the driver when looking for an encoder
for the connector to look through the list of all possible encoders.
