Johan Hovold 86dc1342bc net: phy: micrel: add support for clock-mode select to KSZ8081/KSZ8091
Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select
bit, which is used to select 25 or 50 MHz clock mode.

Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of
this bit is inverted so that setting it enables 25 rather than 50 MHz
mode. Add a new device-tree property
"micrel,rmii-reference-clock-select-25-mhz" to describe this.

Micrel PHY properties.
These properties cover the base properties Micrel PHYs.
Optional properties:
- micrel,led-mode : LED mode value to set for PHYs with configurable LEDs.
Configure the LED mode with single value. The list of PHYs and
the bits that are currently supported:
KSZ8001: register 0x1e, bits 15..14
KSZ8041: register 0x1e, bits 15..14
KSZ8021: register 0x1f, bits 5..4
KSZ8031: register 0x1f, bits 5..4
KSZ8051: register 0x1f, bits 5..4
KSZ8081: register 0x1f, bits 5..4
KSZ8091: register 0x1f, bits 5..4
See the respective PHY datasheet for the mode values.
- clocks, clock-names: contains clocks according to the common clock bindings.
supported clocks:
- KSZ8021, KSZ8031, KSZ8081, KSZ8091: "rmii-ref": The RMII
refence input clock. Used to determine the XI input clock.
