dt-bindings: clock: milbeaut: Drop providers and consumers from example

Convention for examples is to only show what's covered by the binding,
so drop the consumer "socionext,milbeaut-usio-uart" and input clock
provider "fixed-clock" from the example. "socionext,milbeaut-usio-uart"
is also not documented by a schema which caused a warning.
