Problem:
- during the driver initialization, driver will poll fw
for KERNEL_UP in a 30 seconds timeout.
- if the firmware is not ready after 30 seconds,
driver will not be loaded.
Fix:
- change timeout from 30 seconds to 3 minutes.

Problem:
The Linux kernel takes a logical volume offline after a LUN reset. This is
generally accompanied by this message in the dmesg output:
Device offlined - not ready after error recovery
Root Cause:
The root cause is a "quirk" in the timeout handling in the Linux SCSI
layer. The Linux kernel places a 30-second timeout on most media access
commands (reads and writes) that it send to device drivers. When a media
access command times out, the Linux kernel goes into error recovery mode
for the LUN that was the target of the command that timed out. Every
command that timed out is kept on a list inside of the Linux kernel to be
retried later. The kernel attempts to recover the command(s) that timed out
by issuing a LUN reset followed by a TEST UNIT READY. If the LUN reset and
TEST UNIT READY commands are successful, the kernel retries the command(s)
that timed out.
Each SCSI command issued by the kernel has a result field associated with
it. This field indicates the final result of the command (success or
error). When a command times out, the kernel places a value in this result
field indicating that the command timed out.
The "quirk" is that after the LUN reset and TEST UNIT READY commands are
completed, the kernel checks each command on the timed-out command list
before retrying it. If the result field is still "timed out", the kernel
treats that command as not having been successfully recovered for a
retry. If the number of commands that are in this state are greater than
two, the kernel takes the LUN offline.
Fix:
When our RAIDStack receives a LUN reset, it simply waits until all
outstanding commands complete. Generally, all of these outstanding commands
complete successfully. Therefore, the fix in the smartpqi driver is to
always set the command result field to indicate success when a request
completes successfully. This normally isn’t necessary because the result
field is always initialized to success when the command is submitted to the
driver. So when the command completes successfully, the result field is
left untouched. But in this case, the kernel changes the result field
behind the driver’s back and then expects the field to be changed by the
driver as the commands that timed-out complete.

Add PQI reset to driver shutdown callback to work around controller bug.
During an 1.) OS shutdown or 2.) kexec outside of a kdump, the Linux
kernel will clear BME on our controller.
If BME is cleared during a controller/host PCIe transfer, the controller
will lock up.
So we perform a PQI reset in the driver's shutdown callback function to
eliminate the possibility of a controller/host PCIe transfer being
active when the kernel clears BME immediately after calling the driver's
shutdown callback.

The smartpqi firmware will bypass the cache for any request larger than
1MB, so we should cap the request size to avoid any performance
degradation in kernels later than v4.3
This degradation is caused from d2be537c3b,
which changed max_sectors_kb to 1280k, but the hardware is able to
work fine with it, so the true fix should be from smartpqi driver.

The newly added suspend/resume support causes harmless warnings when
CONFIG_PM is disabled:
smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function]
We can avoid the warnings by removing the #ifdef around the handlers and
instead marking them as __maybe_unused, which will let gcc drop the
unused code silently.

When we have turned off RTC support, the smartpqi driver fails to build:
ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined!
This is easily avoided by using the generic 'struct tm' based helper rather
than the RTC specific one. While fixing this, I noticed that even though
the driver uses time64_t for storing seconds, it gets them from the
old 32-bit struct timeval. To address this, we can simplify the code
by calling ktime_get_real_seconds() directly.
