If no boot script was found, expose internal storage over the
USB mass storage gadget to allow easy programming.
This is especially useful when SD cards are inaccessible or when
loading SATA drives.

This patch enables boot to USB storage devices by expanding on the list
of boot devices.
Because the USB startup currently takes a long time, it places USB at
the end of the list of supported devices.
You can over-ride the boot order using the bootdevs environment variable.
For instance, this will make USB the first (highest priority) device:
U-Boot > setenv bootdevs usb mmc sata
U-Boot > saveenv

MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:
cs = (cs | gpio << 8)
This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".
This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.
Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.

This patch fixes allow for the DeviceTree and initrd relocation fixing
the boot of FSL 3.10.9-1.0.0-alpha kernel.
This changes following boards:
- mx6sabreauto
- mx6sabresd
- wandboard
- udoo
- nitrogen6x
- cgtqmx6eval
The reasoning, as explained by Hui Liu, is:
,----
| The FDT blob will be placed at DDR physical addr: 0x11000000. When Linux kernel
| Boot up, it will decompress the compressed kernel image and place the decompressed
| kernel image at the low end of the DDR memory and start running from it. If the
| decompressed kernel image is bigger for example than 16M, it may over written the
| fdt blob which u-boot loaded to the DDR memory @0x11000000 with fdt_addr=0x11000000
|
| To expand the fdt_addr from 0x11000000 to 0x18000000, which can avoid the override
| Since we will not likely have one kernel image larger than 128MB.

Previously, only host1 was supported using an index of 0.
Now, otg has index 0, host1 is 1, host2 is 2, host3 is 3.
Since OTG requires usbmode to be set after reset, I added
CONFIG_EHCI_HCD_INIT_AFTER_RESET to nitrogen6x.h and
mx6qsabreauto.h.
I also added a weak function board_ehci_power to handle
turning power on/off for otg.
Type is type of device connected (USB stick vs Host.)
Init is type of device desired.
Only power up port if type == init == USB_INIT_HOST.
Only return error if type != init.
