[PATCH] drm/arcpgu: remove drm_encoder_slave

[Daniel Vetter <daniel.vetter@ffwll.ch>]

drm_encoder_slave is the old way to write bridge drivers, for i2c
bridges only. It's deprecated, and definitely should not be used in
new drivers.

What's even strange is that arcpgu doesn't even use any of this, it
really only wants a plain normal drm_encoder. Nuke all the surplus
real estate.

v2: Actually git add after compile testing ...
