dt-bindings: mtd: oxnas-nand: remove obsolete bindings

Due to lack of maintenance and stall of development for a few years now,
and since no new features will ever be added upstream, remove the
for OX810 and OX820 nand bindings.

-* Oxford Semiconductor OXNAS NAND Controller
-
-Please refer to nand-controller.yaml for generic information regarding MTD NAND bindings.
-
-Required properties:
- - compatible: "oxsemi,ox820-nand"
- - reg: Base address and length for NAND mapped memory.
-
-Optional Properties:
- - clocks: phandle to the NAND gate clock if needed.
- - resets: phandle to the NAND reset control if needed.
-
-Example:
-
-nandc: nand-controller@41000000 {
-       compatible = "oxsemi,ox820-nand";
-       reg = <0x41000000 0x100000>;
-       clocks = <&stdclk CLK_820_NAND>;
-       resets = <&reset RESET_NAND>;
-       #address-cells = <1>;
-       #size-cells = <0>;
-
-       nand@0 {
-               reg = <0>;
-               #address-cells = <1>;
-               #size-cells = <1>;
-               nand-ecc-mode = "soft";
