From: Francesco Dolcini <francesco.dolc...@toradex.com>
Add configuration for parallel data format register, tc358768 supports
different mapping on the parallel input RGB interface, enable the
configuration for it.
Valid values, and the related meaning, are:
0 = R[7:0], G[7:0], B[7:0]
1 = R[1:0], G[1:0], B[1:0], R[7:2], G[7:2], B[7:2]
2 = 8’b0, R[4:0], G[5:0], B[4:0]
Use 0 by default, consistently with the HW default.
