cortex-a: Fix "Detected core" number is always '0'

Problem
No matter what target->coreid is, it always shows
  Detected core 0 dbgbase: ...

In dap_lookup_cs_component(), it decreases the core index value to zero
in order to find the desired core.
The reference to coreidx is necessary considering "a device which has nested
ROM tables, with each core described in its own table." (by Paul Fertser).
