Update registers as follows:
- Default value of AIP timer is 1ms, and it is easy for some expanders to
cause IO error. Change the value to max value 65ms to avoid IO error for
those expanders.
- A CQ completion will be reported by HW when 4 CQs have occurred or the
aging timer expires, whichever happens first. Sor serial IO scenario, it
will still wait 8us for every IO before it is reported. So in the
situation, the performance is poor. So to improve it, change the limit
time to the least value.
For other scenario, it does little affect to the performance.

Currently we use the IPTT defined in LLDD to identify IOs. Actually for
IOs which are from the block layer, they have tags to identify them. So
for those IOs, use tag of the block layer directly, and for IOs which is
not from the block layer (such as internal IOs from libsas/LLDD), reserve
96 IPTTs for them.

If an SSP/SMP IO times out, it may be actually in reality be
simultaneously processing completion of the slot in
slot_complete_vx_hw().
Then if the slot is freed in slot_complete_vx_hw() (this IPTT is freed
and it may be re-used by other slot), and we may abort the wrong slot in
hisi_sas_abort_task().
So to solve the issue, free the slot after the check of
SAS_TASK_STATE_ABORTED in slot_complete_vx_hw().

SMP/internal IO
If SMP/internal IO times out, we will possibly free the task immediately.
However if the IO actually completes at the same time, the IO completion
may refer to task which has been freed.
So to solve the issue, flush the tasklet to finish IO completion before
free'ing slot/task.

When we fail to analyse the payload of a PRLI response we should reset

When an RSCN gets delayed (or not being sent at all), the transport class
will detect an error, EH kicks in, and eventually will be setting the
device to offline. If we receive an RSCN after that, the device will
stay in 'offline'. This patch allows for an 'offline' to 'blocked'
transition, thereby allowing the device to become active again.

We do not support UPIU of type scsi command yet, while we are using the

The UFS host software uses a combination of a host register set and
Transfer Request Descriptors in system memory to communicate with host
controller hardware. In its mmio space, a separate places are assigned
to UTP Transfer Request Descriptor ("utrd") list, and to UTP Task
Management Request Descriptor ("utmrd") list.
The provided API supports utrd-typed requests: nop out and device
management commands. It also supports utmrd-type requests:
task management requests. Other UPIU types are not supported for now.
We utilize the already existing code for tag and task work queues.
That is, all utrd-typed UPIUs are "disguised" as device management
commands. Similarly, the utmrd-typed UPUIs uses the task management
infrastructure.
It is up to the caller to fill the upiu request properly, as it will be
copied without any further input validations.

For now, just provide an API to allocate and remove ufs-bsg node. We
will use this framework to manage ufs devices by sending UPIU
transactions.
For the time being, implements an empty bsg_request() - will add some
more functionality in coming patches.
Nonetheless, we reveal here the protocol we are planning to use: UFS
Transport Protocol Transactions. UFS transactions consist of packets
called UFS Protocol Information Units (UPIU).
There are UPIU’s defined for UFS SCSI commands, responses, data in and
data out, task management, utility functions, vendor functions,
transaction synchronization and control, and more.
By using UPIUs, we get access to the most fine-grained internals of this
protocol, and able to communicate with the device in ways, that are
sometimes beyond the capacity of the ufs driver.
Moreover and as a result, our core structure - ufs_bsg_node has a pretty
lean structure: using upiu transactions that contains the outmost
detailed info, so we don't really need complex constructs to support it.
