media: dt-bindings: media: Convert Allwinner A10 IR to a schema 

The older Allwinner SoCs have a IR receiver supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

Device-Tree bindings for SUNXI IR controller found in sunXi SoC family
Required properties:
- compatible :
"allwinner,sun4i-a10-ir"
"allwinner,sun5i-a13-ir"
"allwinner,sun6i-a31-ir"
"allwinner,sun50i-a64-ir", "allwinner,sun6i-a31-ir"
"allwinner,sun50i-h6-ir", "allwinner,sun6i-a31-ir"
- clocks : list of clock specifiers, corresponding to
entries in clock-names property;
- clock-names : should contain "apb" and "ir" entries;
- interrupts : should contain IR IRQ number;
- reg : should contain IO map address for IR.
Required properties since A31:
- resets : phandle + reset specifier pair
Optional properties:
- linux,rc-map-name: see rc.txt file in the same directory.
- clock-frequency : IR Receiver clock frequency, in Hertz. Defaults to 8 MHz
if missing.
Example:
ir0: ir@1c21800 {
compatible = "allwinner,sun4i-a10-ir";
clocks = <&apb0_gates 6>, <&ir0_clk>;
clock-names = "apb", "ir";
clock-frequency = <3000000>;
resets = <&apb0_rst 1>;
interrupts = <0 5 1>;
reg = <0x01C21800 0x40>;
linux,rc-map-name = "rc-rc6-mce";
