mb/google/zork/var/shuboz: update USB OC pin mapping

modify USB OC pin setting for Shuboz/Jelboz/Jelboz360

Shuboz/Jelboz:
usb_port_overcurrent_pin[0] = "USB_OC_PIN_0"	# USB C0
usb_port_overcurrent_pin[1] = "USB_OC_PIN_0"	# USB A0
usb_port_overcurrent_pin[2] = "USB_OC_PIN_1"	# USB A1
usb_port_overcurrent_pin[3] = "USB_OC_PIN_1"	# USB C1

Jelboz360:
usb_port_overcurrent_pin[0] = "USB_OC_PIN_0"	# USB C0
usb_port_overcurrent_pin[1] = "USB_OC_PIN_0"	# USB A0
usb_port_overcurrent_pin[2] = "USB_OC_NONE"	# NONE
usb_port_overcurrent_pin[3] = "USB_OC_PIN_1"	# USB C1

BUG=b:182879559
BRANCH=zork
TEST=emerge-zork coreboot, validate the OC mapping.
