Convert the Broadcom BCM2835 SPI0 controller to newer DT
schema. Created DT schema based on the .txt file which had
`comaptible`, `reg`, `interrupts`, `clocks` as required
properties.
Added GPL-2.0 OR BSD-2-Clause License

-Broadcom BCM2835 SPI0 controller
-
-The BCM2835 contains two forms of SPI master controller, one known simply as
-SPI0, and the other known as the "Universal SPI Master"; part of the
-auxiliary block. This binding applies to the SPI0 controller.
-
-Required properties:
-- compatible: Should be one of "brcm,bcm2835-spi" for BCM2835/2836/2837 or
- "brcm,bcm2711-spi" for BCM2711 or "brcm,bcm7211-spi" for BCM7211.
-- reg: Should contain register location and length.
-- interrupts: Should contain interrupt.
-- clocks: The clock feeding the SPI controller.
-
-Example:
-
-spi at 20204000 {
- compatible = "brcm,bcm2835-spi";
- reg = <0x7e204000 0x1000>;
- interrupts = <2 22>;
- clocks = <&clk_spi>;
- #address-cells = <1>;
- #size-cells = <0>;
-};
