Blackfin arch: Start untangling the CPLB handling code.
- Move cache initialization to C from assembly. - Move anomaly workaround for writing [ID]MEM_CONTROL to assembly, so that we don't have to mess around with .align directives in C source. - Fix a bug where bfin_write_DMEM_CONTROL would write to IMEM_CONTROL - Break out CPLB related code from kernel/setup.c into their own file. - Don't define variables in header files, only declare them.
