Convert binding from text format to YAML.
Additions to original text binding:
- add rs485 reference.

-* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
-* i2c as bus
-
-Required properties:
-- compatible: Should be one of the following:
- - "nxp,sc16is740" for NXP SC16IS740,
- - "nxp,sc16is741" for NXP SC16IS741,
- - "nxp,sc16is750" for NXP SC16IS750,
- - "nxp,sc16is752" for NXP SC16IS752,
- - "nxp,sc16is760" for NXP SC16IS760,
- - "nxp,sc16is762" for NXP SC16IS762.
-- reg: I2C address of the SC16IS7xx device.
-- interrupts: Should contain the UART interrupt
-- clocks: Reference to the IC source clock.
- OR (when there is no clock provider visible to the platform)
-- clock-frequency: The source clock frequency for the IC.
-
-Optional properties:
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be two. The first cell is the GPIO number and
- the second cell is used to specify the GPIO polarity:
- 0 = active high,
- 1 = active low.
-- nxp,irda-mode-ports: An array that lists the indices of the port that
- should operate in IrDA mode.
-- nxp,modem-control-line-ports: An array that lists the indices of the port that
- should have shared GPIO lines configured as
- modem control lines.
-
-Example:
- sc16is750: sc16is750@51 {
- compatible = "nxp,sc16is750";
- reg = <0x51>;

- - "nxp,sc16is762" for NXP SC16IS762.
-- reg: SPI chip select number.

You could probably drop this, if it only has one clock it's a bit
redundant.

These labels are not used and should be removed.
Otherwise, conversion looks aight to me.

I don't understand, because there is already a 'clocks' property in
the examples (and also in my real board DTS file) and if I remove it
here it will cause a warning:
serial@51: Unevaluated properties are not allowed ('clocks' was
unexpected)

I was already using 'make DT_CHECKER_FLAGS=-m dt_binding_check', but I incorrectly introduced a space between DT_SCHEMA_FILES= and the filename, and so it was ignored and all schemas were checked, and I lost the warnings in all the noise. I now have fixed it. Also, if someone is interested, I was trying to specify multiple files with DT_SCHEMA_FILES, and I just found out (after analysing the Makefile) that you need to separate them with the ":" character. It would be a good thing to add it to the documentation, I could submit a patch for this if you like.
