Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic SPI controllers over to two separate YAML schemas.

I need to write a schema for this or I'll never stop giving this comment...

Otherwise,

-
-* SPIFC (SPI Flash Controller)
-
-The Meson SPIFC is a controller optimized for communication with SPI
-NOR memories, without DMA support and a 64-byte unified transmit /
-receive buffer.
-
-Required properties:
- - compatible: should be "amlogic,meson6-spifc" or "amlogic,meson-gxbb-spifc"
- - reg: physical base address and length of the controller registers
- - clocks: phandle of the input clock for the baud rate generator
- - #address-cells: should be 1

-
-	spi@c1108c80 {
-		compatible = "amlogic,meson6-spifc";
-		reg = <0xc1108c80 0x80>;
-		clocks = <&clk81>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-	};
-
-* SPICC (SPI Communication Controller)
-
-The Meson SPICC is generic SPI controller for general purpose Full-Duplex
-communications with dedicated 16 words RX/TX PIO FIFOs.
-
-Required properties:
- - compatible: should be:
-	"amlogic,meson-gx-spicc" on Amlogic GX and compatible SoCs.
-	"amlogic,meson-axg-spicc" on Amlogic AXG and compatible SoCs
- - reg: physical base address and length of the controller registers
- - interrupts: The interrupt specifier
- - clock-names: Must contain "core"
- - clocks: phandle of the input clock for the baud rate generator
- - #address-cells: should be 1
- - #size-cells: should be 0
-
-Optional properties:
- - resets: phandle of the internal reset line
-
-See ../spi/spi-bus.txt for more details on SPI bus master and slave devices
-required and optional properties.
-
-Example :
-	spi@c1108d80 {
-		compatible = "amlogic,meson-gx-spicc";
-		reg = <0xc1108d80 0x80>;
-		interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
-		clock-names = "core";
-		clocks = <&clk81>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-	};
