drm_hwcomposer: Add display field to Drmencoder

In the current implementation TryEncoderForDisplay just looks
at the crtc linked to the display, if that's not assigned to
a display it means the encoder could be used, otherwise iterate
to the list of possible_crtcs and find one which is not used.

This logic works fine when you have just one encoder connected to a
crtc but with two or more, like is the case when we attach a writeback
connector, we need to know if we already assigned the encoder to a
display.
