[PATCH 5/8] dt-bindings: serial: 8250: add SpacemiT K3 UART compatible

The SpacemiT K3 UART controller is compatible with the Intel XScale UART.
Add K3 UART binding and allow describing it with a fixed clock-frequency
for now.

The clocks and clock-names properties will be made mandatory in a future
patch, once the K3 clock driver and device tree are merged.
