i.MX53 NAND xload support

[Sascha Hauer]

This series adds NAND xload support for i.MX53 and more specifically
to the Garz+Fricke Vincell board. With this images bigger than the
SoC internal SRAM can be supported and the Vincell can now be enabled
in the imx_v7_defconfig. The existing vincell_defconfig unfortunately
is not obsolete though, since we still need a small image for loading
it with imx-usb-loader.
Also included some misc patches I came up with during working with the
Vincell board.
