Subject: [PATCH 4/9] drm/meson: dw-hdmi: fix incorrect comment in suspend

Comment in suspend says TOP is put in suspend, but the register
poke following is actually de-asserting the reset, like in init.

It is doing the opposite of what the comment says.

Align the comment with what the code is doing for now and add
a FIXME note to sort this out later
