[PATCH] usb: musb-new: Extend Allwinner quirk to newer SoCs

As the comment in musb_regs.h describes, Allwinner saves the
MUSB_CONFIGDATA register, which always return 0 on those SoCs.

This is also true for the H6 and H616, so extend the quirk to those
controllers as well.

This fixes USB peripheral mode on H6 and H616 boards.
