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.
