[PATCH] ARM: dts: imx6sx-sdb: Add QSPI support

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

imx6sx-sdb has two s25fl128s quad spi flash. Add support for them.

There are still some extra patches needed to get s25fl128s supported.

They were already sent into mtd-list, but have not been applied yet.

However, the dts part could go independently.
