MLK-18045-3 drm/imx: dcss: bypass dec400d if 'compressed' is false

When the fb's modifier is 'DRM_FORMAT_MOD_VIVANTE_SUPER_TILED_FC',
the compression state can be changed to non-compress according to
the 'compressed' field value of 'struct dma_metadata' data. At this
moment, the DEC400D should be bypassed.
