cxgbe(4): Changes to the fatal error handler.

* New error_flags that can be used from the error ithread and elsewhere
without a synch_op.
* Stop the adapter immediately in t4_fatal_err but defer most of the
rest of the handling to a task. The task is allowed to sleep, unlike
the ithread. Remove async_event_task as it is no longer needed.
* Dump the devlog, CIMLA, and PCIE_FW exactly once on any fatal error
involving the firmware or the CIM block. While here, dump some
additional info (see dump_cim_regs) for these errors.
* If both reset_on_fatal_err and panic_on_fatal_err are set then attempt
a reset first and do not panic the system if it is successful.

Restore PPS_SYNC in NOTES

This partially reverts e81e77c5a055, leaving the option both in
GENERICs on amd64/arm64/arm, and in global NOTES file. Apparently
this better matches existing practice, where we do not try to hard
