fbdev: fsl-diu-fb: don't use GFP_DMA when calling dmam_alloc_coherent()
dmam_alloc_coherent() allocates the DMA buffer with the device's
addressing limitation in mind; the DMA core picks the zone from the
device's coherent DMA mask and ignores GFP_DMA passed by the caller.
Remove the redundant GFP_DMA flag.
