MLK-17368-3: drm: imx: dcss: Add support for tiled formats

This patch effectively enables DTRC module in DCSS to decode tiled
formats from VPU:
 * uncompressed G1;
 * uncompressed G2;
 * compressed G2;

Compressed G2 formats need to pass on the decompression table offsets,
by using the 'dtrc_dec_ofs' property. This is a 64 bit value like below:

64--------48----------32---------16---------0
|<- chroma table ofs ->|<- luma table ofs ->|
