Attempt to add gamma correction support for imx-ldb. The gamma correction values for the i.mx6 Display Processor registers IPU_DP_GAMMA_C_SYNC/IPU_DP_GAMMA_S_SYNC [1,2] are given as device tree values fsl,gamma-constk and fsl,gamma-slopek (see example values at imx6q-sabrelite.dts calculated as suggested in [3]).
