usb: gadget: Move CONFIG_USB_GADGET_VBUS_DRAW to Kconfig
The description was borrowed from kernel. Definitions were added to defconfig files in a way that "make savedefconfig" generates exactly the same file as used defconfig. Boards using 0 mA as CONFIG_USB_GADGET_VBUS_DRAW value were moved to use 2 mA (as minimal allowed by Kconfig). Signed-off-by: Sam Protsenko <>

+ Some devices need to draw power from USB when they are
+ configured, perhaps to operate circuitry or to recharge
+ batteries. This is in addition to any local power supply,
+ such as an AC adapter or batteries.
+ Enter the maximum power your device draws through USB, in
+ milliAmperes. The permitted range of values is 2 - 500 mA;
+ 0 mA would be legal, but can make some hosts misbehave.
+ This value will be used except for system-specific gadget
+ drivers that have more specific information.
