Remove needless debug handler state.
- "handler_installed" became wrong as soon as the second TRST+SRST
reset was issued ... so the handler was never reloaded after the
reset removed it from the mini-icache.
This fixes the bug where subsequent resets fail on PXA255 (if the
first one even worked, which is uncommon). Other XScale chips
would have problems too; PXA270 seems to have, IXP425 maybe not.
- "handler_running" was never tested; it's pointless.
Plus a related bugfix: invalidate OpenOCD's ARM register cache on reset.
It was no more valid than the XScale's mini-icache. (Though ... such
invalidations might be better done in "SRST asserted" callbacks.)
