/** CM_ARM_GICC_INFO parser function.

  This parser expects FdtBranch to be the "\cpus" node node.
  At most one CmObj is created.
  The following structure is populated:
  typedef struct CmArmGicCInfo {
    UINT32  CPUInterfaceNumber;               // {Populated}
    UINT32  AcpiProcessorUid;                 // {Populated}
    UINT32  Flags;                            // {Populated}
    UINT32  ParkingProtocolVersion;           // {default = 0}
    UINT32  PerformanceInterruptGsiv;         // {Populated}
    UINT64  ParkedAddress;                    // {default = 0}

    UINT64  GICRBaseAddress;                  // {default = 0}

  } CM_ARM_GICC_INFO;

  A parser parses a Device Tree to populate a specific CmObj type. None,
  one or many CmObj can be created by the parser.
  The created CmObj are then handed to the parser's caller through the
  HW_INFO_ADD_OBJECT interface.
  This can also be a dispatcher. I.e. a function that not parsing a
  Device Tree but calling other parsers.

  @param [in]  FdtParserHandle A handle to the parser instance.
  @param [in]  FdtBranch       When searching for DT node name, restrict
                               the search to this Device Tree branch.

  @retval EFI_SUCCESS             The function completed successfully.
  @retval EFI_ABORTED             An error occurred.
  @retval EFI_INVALID_PARAMETER   Invalid parameter.
  @retval EFI_NOT_FOUND           Not found.
  @retval EFI_UNSUPPORTED         Unsupported.
