cortex_a: select APB-AP as the default AP

Debug initialization blindly selects AP#0 as default, which is the AHB-AP
in many cases. This sets the default for target_read/write functions.
However, AHB-AP is the wrong choice, because it bypasses caches on read
and write and also makes some peripherals inaccessible (e.g. l2 outer
caches). This patch explicitely selects the APB-AP (debug_ap) as the
default.
