Blackfin: Split the BF532 BFIN_*_FIO_FLAG() functions to their own header
Split the BF532 machine type BFIN_*_FIO_FLAG() functions to their own header file to avoid circular #include problems as these functions require IRQ flag handling, which requires asm/blackfin.h, which otherwise requires the header file that defines these functions. For good measure, also get rid of the inclusion of asm/blackfin.h from mach/cdefBF532.h (which is circular) and defBF532.h (which is included by asm/blackfin.h before including this header).
