[PATCH v1 3/6] ARM: dts: lan966x: add all flexcom usart nodes

[Michael Walle <michael@walle.cc>]

Add all the usart nodes for the flexcom block. There was already
an usart node for the flexcom3 block. But it missed the DMA
channels. 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.
