[ Upstream commit 62afb379a0fee7e9c2f9f68e1abeb85ceddf51b9 ]
According to the comment in check_fw_ready() we should not check the
IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.
However we check this very field in process_oq() for processing the highest
index interrupt vector. The highest interrupt vector is checked as the FW
is programmed to signal fatal errors through this irq.
Change that function to not check IOP1_READY for those mentioned
controllers, but do check ILA_READY in both cases.
The reason I assume that this was not hit earlier was because we always
allocated 64 MSI(X), and just did not pass the vector index check in
process_oq(), i.e. the handler never ran for vector index 63.

Disabling the SATA drive interface cause kernel panic. When the drive
Interface is disabled, device should be deregistered after aborting all
pending I/Os. Also changed the port recovery timeout to 10000 ms for
PM8006 controller.

When the firmware is not responding, execution of kexec boot causes a system
hang. When firmware assertion happened, driver get notified with interrupt
vector updated in MPI configuration table. Then, the driver will read
scratchpad register and set controller_fatal_error flag to true.
