fsi: Create bus specific probe and remove functions
Introduce a bus specific probe and remove function. For now this only
allows to get rid of a cast of the generic device to an fsi device in
the drivers and changes the remove prototype to return void---a non-zero
return value is ignored anyhow.
The objective is to get rid of users of struct device callbacks
.probe(), .remove() and .shutdown() to eventually remove these.
Until all fsi drivers are converted this results in a runtime warning
about the drivers needing an update because there is a bus probe
function and a driver probe function.

fsi: Make fsi_bus_type a private variable to the core
There are no users of fsi_bus_type outside of fsi-core.c, so make that
variable static, don't export it and drop the declaration from the
public header file.
As there is a usage of fsi_bus_type in fsi_create_device() the
definition of that variable must happen further up in the file to not
have to add a local declaration.

fsi: occ: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
