arm_adi_v5: let dap_lookup_cs_component() to get AP dbgbase

Simplify the code in cortex_a and aarch64 by moving the call to
dap_get_debugbase() inside dap_lookup_cs_component().

This has the further effects:
- dap_get_debugbase() is not referenced outside arm_adi_v5.c and
  becomes static;
- dap_lookup_cs_component() looses one parameter;
- the coreid parameter 'idx' is passed as value;
- the caller in aarch64 don't have and don't print the irrelevant
  value of AP register APID;
- fixes the debug message in the caller in aarch64 to print the
  coreid value instead of always zero.
