Blackfin: kgdb: pass up the CC register instead of a 0 stub

While the CC pseudo register can be deduced from the ASTAT register, make
sure we set its value correctly instead of always stubbing it out as 0.
GDB itself looks at this pseudo register instead of ASTAT, so we have to
supply the right value.
