With old bindings imx_gpc_onecell_data always sets num_domains to 2 so the DISPMIX domain can't actually be referenced. The pd is still defined and pm core shuts it down as "unused" so display can't work.
Converting to new gpc bindings by adding pgc nodes, also reference referencing the newly-defined &pu_disp domain from &lcdif.

There are erratas regarding dispmix on 6sl so this might be wrong

The above power-domain-cells needs to go away when using the new binding.
