Binding for Silicon Labs 570, 571, 598 and 599 programmable
I2C clock generators.

Reference
This binding uses the common clock binding[1]. Details about the devices can be
found in the data sheets[2][3].

Required properties:
 - compatible: Shall be one of "silabs,si570", "silabs,si571",
          "silabs,si598", "silabs,si599"
 - reg: I2C device address.
 - #clock-cells: From common clock bindings: Shall be 0.
 - factory-fout: Factory set default frequency. This frequency is part specific.
   The correct frequency for the part used has to be provided in
   order to generate the correct output frequencies. For more
   details, please refer to the data sheet.
 - temperature-stability: Temperature stability of the device in PPM. Should be
     one of: 7, 20, 50 or 100.

Optional properties:
 - clock-output-names: From common clock bindings. Recommended to be "si570".
 - clock-frequency: Output frequency to generate. This defines the output
      frequency set during boot. It can be reprogrammed during
      runtime through the common clock framework.
 - silabs,skip-recall: Do not perform NVM->RAM recall operation. It will rely
         on hardware loading of RAM from NVM at power on.

Example:
 si570: clock-generator@5d {
  #clock-cells = <0>;
  compatible = "silabs,si570";
  temperature-stability = <50>;
  reg = <0x5d>;
  factory-fout = <156250000>;
