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The deprecated pxa3xx_nand.c driver does not exist anymore, it has been
replaced by marvell_nand.c which has its own up-to-date documentation.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) */
-       };
