Apply driver update from LSI. Many thanks to LSI for continuing to
support FreeBSD.

1) Timeout ioctl command timeouts.
Do not reset the controller if ioctl command completed
successfully.
2) Remove G66_WORKAROUND code (this bug never shipped).
3) Remove unnecessary interrupt lock (intr_lock).
4) Timeout firmware handshake for PChip reset (don't wait forever).
5) Handle interrupts inline.
6) Unmask command interrupt ONLY when adding a command to the pending
queue.
7) Mask command interrupt ONLY after removing the last command from
the pending queue.
8) Remove TW_OSLI_DEFERRED_INTR_USED code.
9) Replace controller "state" with separate data fields to avoid races:

TW_CLI_CTLR_STATE_ACTIVE ctlr->active
TW_CLI_CTLR_STATE_INTR_ENABLED ctlr->interrupts_enabled
TW_CLI_CTLR_STATE_INTERNAL_REQ_BUSY ctlr->internal_req_busy
TW_CLI_CTLR_STATE_GET_MORE_AENS ctlr->get_more_aens
TW_CLI_CTLR_STATE_RESET_IN_PROGRESS ctlr->reset_in_progress
TW_CLI_CTLR_STATE_RESET_PHASE1_IN_PROGRESS ctlr->reset_phase1_in_progress

10) Fix "req" leak in twa_action() when simq is frozen and req is NOT
null.
11) Replace softc "state" with separate data fields to avoid races:
TW_OSLI_CTLR_STATE_OPEN sc->open
TW_OSLI_CTLR_STATE_SIMQ_FROZEN sc->simq_frozen
12) Fix reference to TW_OSLI_REQ_FLAGS_IN_PROGRESS in
tw_osl_complete_passthru()
13) Use correct CAM status values.
Change CAM_REQ_CMP_ERR to CAM_REQ_INVALID.
Remove use of CAM_RELEASE_SIMQ for physical data addresses.
14) Do not freeze/ release the simq with non I/O commands.
When it is appropriate to temporarily freeze the simq with an I/O
command use:
xpt_freeze_simq(sim, 1);
ccb->ccb_h.status |= CAM_RELEASE_SIMQ;
otherwise use:
xpt_freeze_simq(sim, 1);
xpt_release_simq(sim, 1);

Import version 3.60.03.006 of the TWA driver:

This patch does the following:

- Remove un-necessary code that is not even compiling into the driver
under TW_OSL_NON_DMA_MEM_ALLOC_PER_REQUEST defines.
- Remove bundled firmware image and associated "files" entry for tw_cl_fwimg.c
- Remove bundled firmware flashing routines. We now have tw_update userspace
FreeBSD controller flash utility.
- Fix driver crash on load due to shared interrupt.
- Fix 2 lock leaks for Giant lock.
- Fix CCB leak.
- Add support for 9650SE controllers.

Many thanks to 3Ware/AMCC for continuing to support FreeBSD.

Use utc_offset() where applicable, and hide the internals of it
as static variables.

twa corresponding to the 9.3.0.1 release on the 3ware website. This driver has
support for the 9xxxSX controllers, along with the earlier 9xxxS series
controllers.
