Pass the bo flags all the way down to the iommu map code and
translate into the IOMMU flags right before mapping. This crosses the
streams a bit by moving BO level knowledge all the way down into the
MMU driver but it removes IOMMU specific knowledge from the address
space level which will be important when the address space code for
the GPU and the display are merged into one.

copy_from_user_inatomic() is actually a local function that returns
-EFAULT or positive values on error. Otherwise copy_from_user() returns
the number of bytes remaining to be copied. We want to return -EFAULT
here.
I removed an unlikely() because we just did a copy_from_user()
so I don't think it can possibly make a difference.

I/O coherence has some limitations that make it less preferable than

Charger type gets updated in 'smblib_update_usb_type' function
and this should only be called after completion of APSD.
Update the calling sites of 'smblib_update_usb_type' to use
'smblib_get_apsd_result' instead of 'smblib_update_usb_type'.
This ensures charger type doesn't get updated inadvertently.

This reverts 'commit 7961850500 ("soc:qcom: Synchronize
service notifier task's")'
This commit was made for synchronizing two notifier tasks that
were in race in back to back ADSP SSR testing. The change was to
synchronize two threads by queuing both threads in dedicated work
queue. However this caused certain corner case timing issues
in notification to clients of ADSP PD. So, revert it.
