Added the sysfs attribute for non fatal log so that management utility can
get the non fatal dump from driver. The non-fatal error is an error
condition or abnormal behavior detected by the host, or detected and
reported by the controller to the host.The non-fatal error does not stop
the controller firmware and enables it to still respond to host requests.
A typical example of a non-fatal error is an I/O timeout or an unusual
error notification from the controller. Since the firmware is operational,
the error dump information is pushed to host memory (by firmware) upon
request from the host.

In pm80xx driver, the command mpi_set_phy_profile_req is sent by host
during boot to configure the phy profile such as analog setting page, rate
control page. However, the tag is not freed when its response is
received. As a result, 16 tags are missing for each HBA after boot. When
NCQ is enabled with queue depth 16, it needs at least, 15 * 16 = 240 tags
for each HBA to achieve the best performance. In current pm80xx driver with
setting CCB_MAX = 256, the total number of tags in each HBA is 255 for data
IO. Hence, without returning those tags to the pool after boot, some device
will finally be forced to non-ncq mode by ATA layer due to excessive errors
(i.e. LLDD cannot allocate tag for queued task).

A kexec reboot causes the controller fw to assert. This assertion shows up
in two ways, the controller doesn't show up as ready and an interrupt is
waiting as soon as the handler is registered. To resolve this added below
fix:
- Split the interrupt handling setup into two parts, setup and request.
- If the controller ready register indicates not-ready, but that the not
readiness is only on the IOC units we can still try a reset to bring the
system back to the pre-reboot state.

The commands to the controller are sent in fixed sized chunks which are set
per-chip-generation and stashed in iomb_size. The driver fills in structs
matching the register layout and memcpy this to memory shared with the
controller. However, there are two problem cases:
1) Things like phy_start_req are too large because they share the
sas_identify_frame definition with libsas, and it includes the crc
word. This means that it's overwriting the start of the next
command block, that's ok except if it happens at the end of the
shared memory area.
2) Things like set_nvm_data_req which are shared between the HAL
layers. This means that it's sending 'random' data for things that
are in the reserved area. So far we haven't found a case where the
controller FW cares, but sending possible gibberish (for most of
the structures this is in the reserved area so previously zeroed)
is not recommended.

pm80xx_chip_soft_rst starts off with a 500ms delay before it even gets
around to checking for the results of the reset. As long as it's at least
500ms it doesn't matter what the scheduler is doing. The delay in the

to avoid a double-free.
