[PATCH v9 05/10] drm: renesas: rz-du: Count all registered encoders for the possible clones

[Tommaso Merciai]

rzg2l_du_modeset_init() sets the possible clones of every encoder
registered with the DRM device, but builds the mask from the number of
outputs that rzg2l_du_encoders_init() initialized successfully. An
output whose bridge fails to attach after its encoder has been allocated
is skipped and not counted, while its encoder stays registered. The
mask then misses the bit of the last encoders, and
drm_mode_config_validate() warns about bogus possible clones.

Build the mask from the number of registered encoders instead.
