Platforms/AMD/Styx: use anonymous return values for I2Cn::SSCN/FMCN

The compiler complains about the named objects used to hold the return
values of the I2C0 and I2C1 SSCN and FMCN methods:

  Method (SSCN, 0, NotSerialized)
  Control Method should be made Serialized ^
  (due to creation of named objects within)

  Method (FMCN, 0, NotSerialized)
  Control Method should be made Serialized ^
  (due to creation of named objects within)

So return anonymous rather than named packages to shut up the compiler
diagnostic.
