drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callback
Now that we have a callback to check if bridge supports a given mode we can use it in Synopsys Designware HDMI bridge so that we restrict the number of probbed modes to the ones we can actually display. Also, there is no need to use mode_fixup() callback as mode_valid() will handle the mode validation. NOTE: I also had to change the pdata declaration of mode_valid custom callback so that the passed modes are const. I also changed in the platforms I found. Not even compiled it though.
