drm/vc4: hdmi: Move hdmi reset to bind

commit  4eeb931ef20da9521348607f4ebdba04e4655670 from
https://github.com/raspberrypi/linux.git

 rpi-5.10.y

The hdmi reset got moved to a later point in the commit 9045e91a
("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
