Add missing nodes for the flexcom blocks and a node for the SGPIO
block. Then add basic support for the Kontron KSwitch D10.
Microchip, please take a closer look at the compatible strings of
the newly added nodes.
changes since v1:
- fixed indendation
- keep compatible, reg first, move #address-cells and #size-cells
towards the end

The YAML binding (crypto/atmel,at91sam9g46-aes.yaml) mandates the order
of the channels. Swap them to pass devicetree validation.

Add all the remaining usart nodes for the flexcom block. Although the
DMA channels are specified, DMA is not enabled by default because break
detection doesn't work with DMA.
Keep the nodes disabled by default.

Add all I2C nodes of the flexcom IP blocks. The driver supports
FIFO, DMA or both combined. But the latter isn't working correctly.
Thus, skip the fifo-size property for now. DMA is doing single byte
reads in this case.
Keep the nodes disabled by default.

Add basic support for the Kontron KSwitch D10 MMT 6G-2GS which
features 6 Gigabit copper ports and two SFP cages. For now the
following is working:
- Kernel console
- SFP cages I2C bus and mux
- SPI
- SGPIO
- Watchdog

Add basic support for the Kontron KSwitch D10 MMT 6G-2GS which
features 6 Gigabit copper ports and two SFP cages. For now the
following is working:
- Kernel console
- SFP cages I2C bus and mux
- SPI
- SGPIO
- Watchdog
