arm_adi_v5: Convert the AP references from numbers to pointers 

Change the debug_ap and memory_ap fields of the cortex_a target and
the debug_ap field of the cortex_m target to be pointers to the
struct adiv5_ap instead of AP numbers in some known DAP.

This reduces the dependency on the DAP struct in the targets and
enables MEM-AP accesses to take the relevant AP as parameter.
