Subject: [GIT PULL] FSI updates round 4 (last) for 4.19

Hi Greg !

This adds a few fixes for things reported since the last merge,
and the latch batch of changes pending for FSI for 4.19.

That batch is a rather mechanical conversion of the misc devices
into proper char devices.

The misc devices were ill suited, the minor space for them is
limited and we can have a lot of chips in a system creating FSI
devices.

This also allows us to better control (and fix) object lifetime
getting rid of the bad devm_kzalloc() of the structures containing
the devices etc...

Finally, we add a chardev to the core FSI that provides raw CFAM
access to FSI slaves as a replacement for the current "raw" binary
sysfs file which will be ultimately deprecated and removed.

Thanks !
Ben.
