/**
  Performs a bitwise AND of an 8-bit PCI configuration register with an 8-bit
  value, followed a  bitwise inclusive OR with another 8-bit value.

  Reads the 8-bit PCI configuration register specified by Address, performs a
  bitwise AND between the read result and the value specified by AndData,
  performs a bitwise inclusive OR between the result of the AND operation and
  the value specified by OrData, and writes the result to the 8-bit PCI
  configuration register specified by Address. The value written to the PCI
  configuration register is returned. This function must guarantee that all PCI
  read and write operations are serialized.

  If Address > 0x0FFFFFFF, then ASSERT().

  @param  Address Address that encodes the PCI Bus, Device, Function and
                  Register.
  @param  AndData The value to AND with the PCI configuration register.
  @param  OrData  The value to OR with the result of the AND operation.

  @return The value written back to the PCI configuration register.
