x86: tangier: Make _CRS for BTH0 Serialized to avoid warning

ASL compiler warns:

  ASL     board/intel/edison/dsdt.asl
  board/intel/edison/dsdt.asl.tmp    238:             Method (_CRS, 0, NotSerialized)
  Remark   2120 -      Control Method should be made Serialized ^  (due to creation of named objects within)

Do as suggested by ASL compiler.
