colibri_vf: use same NAND clock as Linux uses
Currently a divider of 6 has been used, leading to following NAND Flash Controller (NFC) clocks: VF61: 27.7 MHz (166.7MHz bus clock) VF50: 22 MHz (132MH
colibri_vf: use same NAND clock as Linux uses
Currently a divider of 6 has been used, leading to following NAND Flash Controller (NFC) clocks: VF61: 27.7 MHz (166.7MHz bus clock) VF50: 22 MHz (132MHz bus clock)
The NAND Flash Memory used on VF50 allows to use clock speed of up to 33MHz, while the Flash Memory of VF61 allows 50MHz. We can use the same divider of 4 on both modules to configure the maximal possible clock speeds: VF61: 41.7 MHz VF50: 33 MHz

colibri_vf: cleanup USB clock initialization
Use the same preprocessor define to enable clocks as we use to enable the driver. Make sure that the necessary PLL's are on (they get enabled by boot ROM by default, so this is more for completness).

Use device-tree fixup to communicate the MTD partitions to the kernel. U-Boot's mtdparts environment variable will be used as partition source for the device-tree based partition table too.

colibri_vf: Enable board specific USB initialisation for USB pen gpio
Add IOMUX for the pad used as USB pen. This needs to be driven low for the Iris and Viola boards where it is pulled up high by default. This is required for the USB host functionality to work on these boards. Use the board specific weak initialisation function, to drive the pin low which would be called on "usb start".
