drm: xlnx: Select VIDEOMODE_HELPERS when DRM_XLNX_PL_DISP is selected

Select the VIDEOMODE_HELPERS when DRM_XLNX_PL_DISP is selected in
menuconfig. This fixes the compilation error of undefined reference to
drm_display_mode_to_videomode in the Xilinx PL Display driver.

This is also added to DRM_XLNX_MIXER as the same API is being used
there.
