google/reef: Enable I2C TPM

Enable the I2C based TPM on the reef board at
bus 2 and address 0x50.

This makes vboot functional without needing MOCK_TPM and
results in the following in the SSDT:

Device (TPMI)
{
  Name (_HID, "GOOG0005")  // _HID: Hardware ID
  Name (_UID, Zero)  // _UID: Unique ID
  Name (_DDN, "I2C TPM")  // _DDN: DOS Device Name
  Method (_STA, 0, NotSerialized)  // _STA: Status
  {
    Return (0x0F)
  }

  Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
  {
    I2cSerialBus (0x0050, ControllerInitiated, 0x00061A80,
                  AddressingMode7Bit, "\\_SB.PCI0.I2C2",
                  0x00, ResourceConsumer)
    Interrupt (ResourceConsumer, Edge, ActiveLow, Exclusive)
    {
      0x00000039
    }
  })
}
