David Brownell <david-b@pacbell.net> Accomodate targets which don't support various target-specific 

reset operations.  Maybe they can't; or it's a "not yet" thing.

Note that the assert/deassert operations can't yet trigger for
OMAP3 because resets currently include JTAG reset in all cases,
resetting the ICEpick and thus disabling the TAP for Cortex-A8.
