dt-bindings: pinctrl: marvell,armada3710-xb-pinctrl: fix 'usb32_drvvbus0' group name

The trailing '0' character of the  'usb32_drvvbus0' pin group got removed
during converting the bindings to DT schema.

  $ git grep -n usb32_drvvbus v6.18
  v6.18:Documentation/devicetree/bindings/pinctrl/marvell,armada-37xx-pinctrl.txt:106:group usb32_drvvbus0
  v6.18:drivers/pinctrl/mvebu/pinctrl-armada-37xx.c:195:  PIN_GRP_GPIO("usb32_drvvbus0", 0, 1, BIT(0), "drvbus"),

  $ git grep -n usb32_drvvbus v6.19-rc1
  v6.19-rc1:Documentation/devicetree/bindings/pinctrl/marvell,armada3710-xb-pinctrl.yaml:91:                usb2_drvvbus1, usb32_drvvbus ]
  v6.19-rc1:drivers/pinctrl/mvebu/pinctrl-armada-37xx.c:195:      PIN_GRP_GPIO("usb32_drvvbus0", 0, 1, BIT(0), "drvbus"),

Add it back to match the group name with the one the driver expects.
