With DAP WAIT support, it's no longer necessary to start with slow
JTAG clock.

Felipe Balbi b1f3e89970 tcl: icepick: add icepick_d_set_coreid
this is just to avoid open coding that in
icepick_d_tapenable. Cleanup only, no functional
changes.

Felipe Balbi 1d8c36e16a tcl: target: am437x: pass coreid
This commit is only for the sake of completeness as
default coreid is zero. In any case, coreids 1-4 are
used for the different PRU cores inside the SoC.

Felipe Balbi beb61c6999 target: am437x: use more descriptive names
Use more descriptive names for JRC and DAPs
so they more closely match documentation.

For example there's no Cortex A9 DAP, that's
the DebugSS DAP where Cortex A9 target sits. In
that same DAP we have have ETM, STM and both
dual-PRU subsystems.

Felipe Balbi d85a0a6a0c tcl: am437x: disable watchdog on reset-end
sometimes, watchdog might be left running and
it could expire in the middle of a debug session,
to prevent that, just make sure to disable watchdog
on reset-end if current state is 'halted'.

Felipe Balbi 589affe35b tcl: target: am437x.cfg: pass correct dbgbase
Since commit ec9ccaa288 (arm_adi_v5: make dap_lookup_cs_component()
traverse subtables and handle multicore) AM437x devices can't be used
with OpenOCD anymore. The reason is that dbgbase used to be set to zero
before that commit and that just happens to work with AM437x devices.

A more robust solution is to pass correct dbgbase when creating the
target, which this commit does.
