aries | p1: drivers: usb: gadget: update power configuration

 bmAttributes

	Specify power parameters for the configuration.
	If a device is self powered, it sets D6. Bit D7 was used
	in USB 1.0 to indicate a bus powered device, but this is
	now done by bMaxPower. If a device uses any power from the
	bus, whether it be as a bus powered device or as a self
	powered device, it must report its power consumption in bMaxPower.
	Devices can also support remote wakeup which allows the device
	to wake up the host when the host is in suspend.

 bMaxPower

	Defines the maximum power the device will drain from the bus.
	This is in 2mA units, thus a maximum of approximately 500mA
	can be specified. The specification allows a high powered bus
	powered device to drain no more than 500mA from Vbus. If a
	device loses external power, then it must not drain more than
	indicated in bMaxPower. It should fail any operation it cannot
	perform without external power

 reference

	these values is present at latest official samsung kernel (OSRC)
	released for arm arch exynos devices
