Startup now mostly works, except that the initial target state
is "unknown" ... previously, it refused to even start.
Getting that far required fixing the ircapture value (which
can never have been correct!) and the default JTAG clock rate,
then providing custom reset script.
The "reset" command is still iffy. DCSR updates, and loading
the debug handler, report numerous DR/IR capture failures.
But once that's done, "poll" reports that the CPU is halted
(which it shouldn't be, this was "reset run"!), due to the
rather curious reason "target-not-halted".
Summary: you still can't debug these parts, but it's closer.

This function is used by the SheevaPlug installer to flash the
erase and re-flash the U-Boot environment in the NAND Flash.

This is clearly noted in the hardware spec (section 5.2.3); it
works around a chip erratum: "If the MPU_RESET signal is used,
it may cause the EMIFS bus to lock."
I seem to have a board with such an initial build. The chip
is labeled XOMAP. Presumably, parts without that "X" prefix
(eXperimental) resolve this.

Without some extra delay after releasing SRST, we seemed to
be trying to talk to the TAP before it was ready to respond.

The model is that this fires after scanchain verification, when it's
safe to call "jtag tapenable $TAPNAME". So it will fire as part of
non-error paths of "init" and "reset" command processing. However it
will *NOT* trigger during "jtag_reset" processing, which skips all
scan chain verification, or after verification errors.
ALSO:
- switch DaVinci chips to use this new mechanism
- log TAP activation/deactivation, since their IDCODEs aren't verified
- unify "enum jtag_event" scripted event notifications
- remove duplicative JTAG_TAP_EVENT_POST_RESET

It can be sped up later, once it's known the PLLs are active.
Note that modern tools from TI all use adaptive clocking; and
that if that's done with OpenOCD, "too fast" is also a non-issue.

Update the board config for the DaVinci DM355 EVM so the reset-init
event handler does the rest of the work it should do:
- minor PLL setup bugfixes
- initialize the DDR2 controller
- probe both NAND banks
- initialize UART0
- enable the icache

TRST signals, so
defining ntrst_delay is pointless; don't.
At least the LM3S3748 eval board doesn't need nsrst_delay
either; remove that too.
