vc4_hdmi: Move hdmi reset to bind

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

The hdmi reset got moved to a later point in
"drm/vc4: hdmi: Add reset callback"

which now occurs after vc4_hdmi_cec_init
and so tramples the setup of registers like
HDMI_CEC_CNTRL_1

This only affects pi0-3 as on pi4 the cec
resgisters are in a separate block
