[PATCH v9 61/61] drm/connector: Drop redundant max_bpc field

Now that all users migrated to the new drmm_connector_hdmi_init()
signature, max_bpc is provided through struct drm_connector_hdmi_funcs,
a reference to which is already stored in drm_connector_hdmi.

Drop the redundant connector->max_bpc field and point its users to
hdmi.funcs->max_bpc instead.
