I didn't do anything clever here.
Reading the cortex_a9/a8.c logs it looked like Cortex A8 had simply
been abandoned, so I copied cortex_a9.c onto cortex_a8.c, did a quick
search and replace job and deleted cortex_a9.c.
Any objections?
Insights?
Does this look OK?
Are all the changes that went into cortex_a9.c appropriate for cortex_a8?

arm_adi_v5: add/move apsel member in struct adiv5_dap
This patch tries to make some order in "apsel" mess.
"dap apsel" command was quite useless (and broken) by itself.
With this patch we can use it to select between AHB or APB memory access
(previous patch 05ab8bdb813acdcd74afa71d6656c2df816cb230 was somehow
broken).
- moves member apsel (in struct adiv5_dap) to ap_current
- adds apsel member
this strange choice is made trying to keep coherence in "dap apsel" command
and to keep compatibility with other code (for example cortex_a8).

cortex_a9: move dap_ap_select to arm_avi_v5
dap_ap_select was used in the code at various points, but that can lead to
confusion, without any knowledge of what AP is really selected at some
points.
Some bugs derive from this (for example md/mw doesn't work well after
issueing "dap apsel" command).
Moving it to arm_adi_v5.c (using mem_ap_sel* functions instead of mem_ap_*)
make the code more clear and more easier to maintain.
In the future it should be made "static" to avoid its use outside arm_adi_v5
One further benefit is the various goto has been removed as well

cortex_a9: implement read/write memory through APB-AP
This patch adds read/write capability to memory addresses not
accessible through AHB-AP (for example "boot ROM code").
To select AHB or APB, a "dap apsel" command must be issued:
dap apsel 0 -> following memory accesses are through AHB
dap apsel 1 -> following memory accesses are through APB
NOTE: at the moment APB memory accesses are very slow, compared
to AHB accesses. Work has to be done to get it faster (for
example LDR/STR instead od LDRB/STRB)
