MLK-20506 gpu: imx: imx8_dprc: Set CROP_ULC_X/Y to be zero for linear fb
Nonzero CROP_ULC_X/Y are only valid for tile framebuffer cropping.
Thus, we should set them to be zero for linear framebuffer, otherwise,
an on-the-fly switch from tile framebuffer(with cropping enabled) to
linear framebuffer would cause hardware malfunction.
