[PATCH 05/10] dt-bindings: leds: kinetic,ktd202x: Add Etek ET6326

[Joseph Telaak via B4 Relay]

From: Joseph Telaak <joseph@xxxxxxxxxx>

The Etek ET6326 is a 3 channel LED driver with the register map, the I2C
address and the current steps of the KTD2026. It only differs in the
flash period, which is (Reg1 + 1) * 128 ms instead of 256 ms + Reg1 *
128 ms, so a KTD2026 driver runs it with blink periods that are 128 ms
off. Document it with the KTD2026 as fallback.

The ET6326 drives the status LED of the GL.iNet GL-SFT1200 (Opal).
