Blackfin arch: cplb and map header file cleanup

- remove duplicated defines for the BF561 - generalize L2 support (so that it works for BF54x) and mark it executable - add support for reading/executing the Boot ROM sections (since it has data/functions we may need at runtime) - and fixup names for each map Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
