dt-bindings: mtd: remove pxa3xx NAND controller documentation
The deprecated pxa3xx_nand.c driver does not exist anymore, it has been replaced by marvell_nand.c which has its own up-to-date documentation.

-PXA3xx NAND DT bindings
-
-Required properties:
-
- - compatible: Should be set to one of the following:
- marvell,pxa3xx-nand
- marvell,armada370-nand
- marvell,armada-8k-nand
- - reg: The register base for the controller
- - interrupts: The interrupt to map
- - #address-cells: Set to <1> if the node includes partitions
- - marvell,system-controller: Set to retrieve the syscon node that handles
- NAND controller related registers (only required
- with marvell,armada-8k-nand compatible).
-
-Optional properties:
-
- - dmas: dma data channel, see dma.txt binding doc
- - marvell,nand-enable-arbiter: Set to enable the bus arbiter
- - marvell,nand-keep-config: Set to keep the NAND controller config as set
- by the bootloader
- - num-cs: Number of chipselect lines to use
- - nand-on-flash-bbt: boolean to enable on flash bbt option if
- not present false
- - nand-ecc-strength: number of bits to correct per ECC step
- - nand-ecc-step-size: number of data bytes covered by a single ECC step
-
-The following ECC strength and step size are currently supported:
-
- - nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- - nand-ecc-strength = <4>, nand-ecc-step-size = <512>
- - nand-ecc-strength = <8>, nand-ecc-step-size = <512>
-
-Example:
-
- nand0: nand@43100000 {
- compatible = "marvell,pxa3xx-nand";
- reg = <0x43100000 90>;
- interrupts = <45>;
- dmas = <&pdma 97 0>;
- dma-names = "data";
- #address-cells = <1>;
-
- marvell,nand-enable-arbiter;
- marvell,nand-keep-config;
- num-cs = <1>;
-
- /* partitions (optional) */
- };
