NAND flash chips.
Required properties:
- compatible : should be "fsl,<chip>-gpmi-nand"
- compatible : should be "fsl,<chip>-gpmi-nand", chip can be:
* imx23
* imx28
* imx6q
* imx6sx
* imx7d
- reg : should contain registers location and length for gpmi and bch.
- reg-names: Should contain the reg names "gpmi-nand" and "bch"
- interrupts : BCH interrupt number.

and GPMI DMA channel ID.
Refer to dma.txt and fsl-mxs-dma.txt for details.
- dma-names: Must be "rx-tx".
- clocks : clocks phandle and clock specifier corresponding to each clock
specified in clock-names.
- clock-names : The "gpmi_io" clock is always required. Which clocks are
exactly required depends on chip:
* imx23/imx28 : "gpmi_io"
* imx6q/sx : "gpmi_io", "gpmi_apb", "gpmi_bch", "gpmi_bch_apb", "per1_bch"
