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

Browse Source 
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>;
};
