drm_hwcomposer: Chose preferred mode with type DRM_MODE_TYPE_PREFERRED
According to the Linux Kernel: "DRM_MODE_TYPE_PREFERRED: Preferred mode,
usually the native resolution of an LCD panel. There should only be
one preferred mode per connector at any given time."
Will use it during preferred mode choice.
