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).

short story: if the JTAG clock is too high, then the
behavior will be flaky and kludging the code may
seem to make things beter, but really it's just a red
herring.

normal code should not call jtag_get_error(), but rather check
the return code from jtag_execute_queue().

So don't use the name "swjdp" for all DAPs; rename to
plain old "dap", which *is* always correct.

jtag_get/set_end_state() is now deprecated.
There were lots of places in the code where the end state was
unintentionally modified.
The big Q is whether there were any places where the intention
was to modify the end state. 0.5 is a long way off, so we'll
get a fair amount of testing.

Unclutter arm_adi_v5.c by moving most transport-specific code
to a transport-specific files adi_v5_{jtag,swd}.c ... it's not
a full cleanup, because of some issues which need to be addressed
as part of SWD support (along with implementing the DAP operations
on top of SWD transport):
- The mess where mem_ap_read_buf_u32() is currently coded to
know about JTAG scan chains, and thus needs rewriting before
it will work with SWD;
- Initialization is still JTAG-specific
Also move JTAG_{DP,ACK}_* constants from adi_v5.h to the JTAG
file; no other code should care about those values.
