Replace usages of pmb:kconfigcheck-* options with
pmb:kconfigcheck-community which will be required for all devices in
community/main category. This ensures more consistent features &
behavior across devices.
Disable HDMI as workaround, as it seems to be buggy when HDMI is
unplugged. It's apparently in DRM_MODE_CONNECTED state, but without size
and with no modes. According to Guido from Phosh this is a bug and
should be fixed in the kernel. By disabling this until it is fixed, we
get Phosh working again.
