imx-drm does not report correct info in fbset

Hi Philipp/Sascha,

When I enable the parallel display on a mx53qsb, I noticed that fbset
does not report the correct information:

mode "800x480-0"
        # D: 0.000 MHz, H: 0.000 kHz, V: 0.000 Hz
        geometry 800 480 800 480 16
        timings 0 0 0 0 0 0 0
        accel true
        rgba 5/11,6/5,5/0,0/0
endmode

I haven't started debugging this, but just would like to check if this
is a known issue with the imx-drm driver.

Thanks,

Fabio Estevam
