[U-Boot] [PATCH] arm: mx6: gw_ventana: Change clock init to enable NAND related clocks

[U-Boot] [PATCH] arm: mx6: gw_ventana: Change clock init to enable NAND related clocks

[Stefan Roese]

Otherwise NAND booting is likely to fail. Since this disables the NAND related
clocks and SPL can't load the main U-Boot from NAND.

This problem was introduced with this patch:

e25fbe3f (gw_ventana: Move the DCD settings to spl code)
