dt-bindings: mmc: brcm,kona-sdhci: convert to YAML 



Convert Broadcom Kona family SDHCI controller bindings to DT schema.

Changes during conversion:
  - also mark reg and interrupts as required
  - drop deprecated compatible (it's been deprecated for ~10 years)

Broadcom BCM281xx SDHCI



This file documents differences between the core properties in mmc.txt

and the properties present in the bcm281xx SDHCI



Required properties:

- compatible : Should be "brcm,kona-sdhci"

- DEPRECATED: compatible : Should be "bcm,kona-sdhci"

- clocks: phandle + clock specifier pair of the external clock



Refer to clocks/clock-bindings.txt for generic clock consumer properties.



Example:



sdio2: sdio@3f1a0000 {

	compatible = "brcm,kona-sdhci";

	reg = <0x3f1a0000 0x10000>;

	clocks = <&sdio3_clk>;

	interrupts = <0x0 74 0x4>;

};
