[Blackfin] arch: relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used.
relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used. this way when we change CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files rather than a whole bunch that implicitly include cplb.h. this will also remove the ability to clear the swapcount on the fly, but i really dont think that functionality is important. ultimate goal is for CONFIG_MEM_SIZE to go away and calculate this value on the fly based on what u-boot programmed for us.
