[PATCH] Uninitialized KMSDRM fixes

On our imx6 based etnaviv platform when CONFIG_DRM_FBDEV_EMULATION is disabled KMSDRM is not initialized by default, thus SDL2 can't use it. The attached patch fixes few things:

    * Search for valid encoder in connector when it doesn't have an
      encoder ID set.

    * Search for valid CRTC in resources and encoder's possible CRTCs
      when encoder doesn't have one set.

    * Select default mode if CRTC doesn't have a valid one.

    * Pick current_mode's W/H/Refresh Rate basing on current and
      valid CRTC mode, not the saved one.
