mb/google/volteer: Configure Delbin USB2 ports for Type C
Two USB2 ports 4 and 9 are assigned to type C connectors on Delbin board. This update configures these USB2 ports for Type C which will allow USB2 port reset message upstream from PCH to CPU to recover a USB3 device that downgraded to USB2 to upgrade back to USB3.
BUG=b:176575892 TEST=Booted to kernel on Delbin board and verified usb2 port reset message enable bits through pch xhci_mmio_base + R_XHCI_MEM_U2PRM_U2PRDE where the offset register R_XHCI_MEM_U2PRM_U2PRDE has value 0x92f4. Validated various USB3 devices enumeration.
