bnxt_en: Handle firmware reset.
Add the bnxt_fw_reset() main function to handle firmware reset. This
is triggered by firmware to initiate an orderly reset, for example
when a non-fatal exception condition has been detected. bnxt_fw_reset()
will first wait for all VFs to shutdown and then start the
bnxt_fw_reset_task() work queue to go through the sequence of reset,
re-probe, and re-initialization.
The next patch will add the devlink reporter to start the sequence and
call bnxt_fw_reset().
