Javier Carrasco fdaf4c5acf dt-bindings: rtc: pcf2123: convert to YAML
Convert the existing txt binding to the preferred YAML format.

The pcf2123 node may contain SPI settings such as spi-cs-high and
spi-max-frequency, which keeps it from being added to the trivial-rtc
binding with its current definition. Add a reference to
spi-peripheral-props.yaml to account for that.

The "interrupts" property was missing in the binding although it is
already supported. Add the missing property in the new binding.
