Thanks,

Beware we will need to keep old DT with new kernel functional for a while,
do removal of component & HHI in meson_dw_hdmi would need to wait for multiple
kernel releases.

A migration step would be to add a phandle to hhi right now, so we can drop
components earlier, then in a second time add a proper PHY and then mark
the hhi reg as deprecated.
