Zhen Lei 8f082dcf2c dt-bindings: serial: Change to reference the kernel-defined serial.yaml
The /schemas/serial.yaml from dt-schema only has the property $nodename,
whereas the kernel-defined /schemas/serial/serial.yaml contains more
useful properties, support for more complex application scenarios.

For example:
1) The property "current-speed" in fsl-lx2160a.dtsi
2) The subnode "bluetooth" in hi3660-hikey960.dts
