drm/imx: imx-ldb: honor 'native-mode' property when selecting video mode from DT
This patch allows to select a specific video mode from a list of modes
defined in DT by setting the 'native-mode' property appropriately.
This change does not affect the behaviour of existing platforms, since
they either:
- have just one display-timings subnode
- have the native-mode property pointing to the first entry
- let the bootloader select the appropriate timing
