drm/vc4: hdmi: Move hdmi reset to bind
The hdmi reset got moved to a later point in the commit 9045e91a476b
("drm/vc4: hdmi: Add reset callback").
However, the reset 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 registers are in a separate
block
Fixes: 9045e91a476b ("drm/vc4: hdmi: Add reset callback")
