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).

+	   configured, perhaps to operate circuitry or to recharge
+	   batteries.  This is in addition to any local power supply,

+	   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
