Add Kamstrup OMNIA Flex Concentrator compatibles to the schema
so we can make use of them for the validation.

This adds support for the OMNIA Flex Concentrator product
from Kamstrup A/S. It's providing radio mesh communication
infrastructure for smart electricity meters.

Kamstrup OMNIA is a modular and scalable smart grid platform.

Changes since version 2:
- Found root cause of Ethernet PHY auto detect issue and created
  a mdio patch series that resolves the issue.
  https://lore.kernel.org/netdev/20200730195749.4922-1-bruno.thomsen@gmail.com/
- Ethernet PHY reset is using new MDIO bus reset.
- Ethernet PHY interrupt added.
- Removed SION from a few GPIOs used for Ethernet PHY.

Changes since version 1:
- Sorted labeling nodes.
- Sorted pinctrl entries.
- Removed deprecated fec phy reset properties.
- Added mdio phy reset properties.
- Disabled phy type auto detection and added note to commit message.
- Fixed two comment typos.

'make dtbs_check' reports the following issue:

    compatible: ['kam,imx7d-flex-concentrator-mfg', 'kam,imx7d-flex-concentrator', 'fsl,imx7d'] is too long

I think dropping 'kam,imx7d-flex-concentrator' should fix it.

gpio-leds: 'hmi-b-green', 'hmi-b-red', 'hmi-c-green', 'hmi-c-red', 'hmi-d-green', 'hmi-d-red' do not match any of the regexes: '(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
