mpi3mr: Enhance Controller Enable Retry Logic in Host Drivers

[chandrakanth.patil_broadcom.com]

Summary

This patch improves the retry logic during the IOC enable process.
If a controller faults or if the reset history bit is detected during
the ready status check, the driver will retry initialization up to three
times or until 510 seconds have passed.

A soft reset will also be issued if the controller is detected while
waiting for the ready status.

This enhances reliability during controller initialization.

This seems OK, but I can't check that the details done here matches the firmware running on the card.
I'll trust the vendor, though, to get this right. The FreeBSD details look good though.

Thank you.
