usb: gadget: aspeed: Fix probe regression
Since commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets"),
the gadget devices are proper driver core devices, which caused each
device to request pinmux settings:
aspeed_vhub 1e6a0000.usb-vhub: Initialized virtual hub in USB2 mode
aspeed-g5-pinctrl 1e6e2080.pinctrl: pin A7 already requested by 1e6a0000.usb-vhub; cannot claim for gadget.0
aspeed-g5-pinctrl 1e6e2080.pinctrl: pin-232 (gadget.0) status -22
aspeed-g5-pinctrl 1e6e2080.pinctrl: could not request pin 232 (A7) from group USB2AD on device aspeed-g5-pinctrl
g_mass_storage gadget.0: Error applying setting, reverse things back
The vhub driver has already claimed the pins, so prevent the gadgets
from requesting them too by setting the magic of_node_reused flag. This
causes the driver core to skip the mux request.
