Block layer RPM is enabled for the genernal UFS SCSI devices when they are
probed by their driver. However block layer RPM is not enabled for UFS
well-known SCSI devices.
As UFS SCSI devices have their corresponding BSG char devices, accessing
a BSG char device via IOCTL may send requests to its corresponding SCSI
device through its request queue. If BSG IOCTL sends a request to a
well-known SCSI device when hba is not runtime active, due to block layer
RPM is not eanbled for the well-known SCSI devices, hba, which is at the
top of a scsi device's parent chain, shall not be resumed, then unexpected
error would happen.
This change enables block layer RPM for the well-known SCSI devices, so
that block layer can handle RPM for the well-known SCSI devices just like
for the general SCSI devices.

wait_for_completion_interruptible() returns ERESTARTSYS when
the device goes to low power mode.
The SPU subsystem is shutdown on deep low power mode,
so the interrupted operation is not recoverable.
return EINTR to user space to propagate the error to the user app.

The sample_ms should never be larger than the devfreq polling
interval. If userspace tries to configure this invalid
configuration, return an error.
Devfreq polling interval should be always greater then the
sample_ms add check in the governor interval event to update
the polling interval accordingly.

[avajid@codeaurora.org: Replaced snprintf with scnprintf]
Signed-off-by: Amir Vajid <avajid@codeaurora.org>
HV-haptics module with V2 revision supports 640 bytes FIFO memory and
each byte contains a FIFO sample. There are 4 adjacent SPMI registers
which can be used for filling 4 FIFO samples together by using SPMI
burst writes and also a single register for filling FIFO samples while
the samples are less than 4.
Also update the logic of writing FIFO samples: Check the available
FIFO memory first and then write FIFO with samples no more than the
available FIFO memory space. With this new logic, it's not necessory
to read FIFO_READY_STS register before writing FIFO samples and this
helps on reducing FIFO writing latency.

The mem-buf driver doesn't strictly depend on the secure
buffer functionality. For example, it can still be functional
in environments where it is used purely for requesting memory
from other VMs. Thus, remove the dependency.
