arm_adi_v5: make dap_lookup_cs_component() traverse subtables and handle multicore

Browse Source 
When looking for a debug base address of a core, one should search
through all the ROM tables, not just the top-level one.

This code also assumes that the first found entry (in a depth-first
search) will correspond to core 0, the second to core 1 etc.

The patch is supposed to be an alternative implementation of
http://openocd.zylin.com/#/c/1313/.
