[U-Boot] [PATCH] sunxi: Use "usb start" rather then "run usb_init" for preboot with usb-kbd

[Hans de Goede]

In an effort to avoid usb getting scanned twice when using an usb keyboard,
and booting from usb, I've set preboot to "run usb_init" in the
CONFIG_USB_KEYBOARD patch.

This is wrong however, as it causes usb to not be scanned (and the keyboard to
not be found) if an "env save" is done, since then the env
contains usb_need_init=false.

This commit fixes this by changing the preboot value to "usb start", so that
usb gets scanned for a keyboard unconditionally when usb-keyboard support is
enabled.
