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

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Properties which are child node definitions need to have an explict
