[PATCH v3 7/9] mfd: axp20x: add USB power supply mfd cell to AXP813

[Chen-Yu Tsai <wens-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Quentin Schulz <quentin.schulz-LDxbnhwyfcJBDgjK7y7TUQ@public.gmane.org>

The AXP813 has a VBUS power input. Now that the axp20x_usb_power driver
supports this variant, we can add an mfd cell for it to use it.
