Move the native-mode property inside the display-timings node.

According to
Documentation/devicetree/bindings/display/panel/display-timing.txt.
native-mode is a property of the display-timings node.

If it's located outside of display-timings, the native-mode setting is
ignored and the first display timing is used (which is a problem only if
someone adds another display timing).

In addition to the PHYTEC phyCORE-i.MX 6UL the PHYTEC phyBOARD-Segin is
also available with the PHYTEC phyCORE-i.MX 6ULL. So this adds support
for this SOM and its baseboards.

It comes in a full featured option with either NAND flash or eMMC and in
a low cost option only available with NAND flash.

The hardware specs are:

 - Full featured with NAND or eMMC:
    * i.MX 6ULL Y2
    * 512MB DDR3 memory
    * 512MB NAND flash or 4GB/8GB eMMC
    * Dual 10/100 Ethernet
    * USB Host and USB OTG
    * RS232
    * MicroSD external storage
    * Audio, RS232, I2C, SPI, CAN headers
    * Further I/O options via A/V and Expansion headers

 - Low cost with NAND:
    * i.MX 6ULL Y0
    * 256MB DDR3 memory
    * 128MB NAND flash
    * Single 10/100 Ethernet
    * USB OTG
    * RS232
    * MicroSD external storage
    * I2C
    * Further I/O options via Expansion headers

map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
