drm/vc4: hdmi: Use the connector state pixel rate for the PHY 
The PHY initialisation parameters are not based on the pixel clock but
the TMDS clock rate which can be the pixel clock in the standard case,
but could be adjusted based on some parameters like the bits per color.

Since the TMDS clock rate is stored in our custom connector state
already, let's reuse it from there instead of computing it again.

drm/vc4: hdmi: Add PHY init and disable function 
The HDMI PHY in the BCM2711 HDMI controller is significantly more
complicated to setup than in the older BCM283x SoCs.

Let's add hooks to enable and disable the PHY.
