spmi_controller_probe()
spmi_controller_probe() assigns a parent device and an OF node to an
SPMI controller. However, the operations are not needed as they are
already assigned in spmi_controller_alloc(). Thus, remove the duplicated
assignments. An unnecessary OF node reference acquisition is also
dropped by this patch.

'nr' member of struct spmi_controller, which serves as an identifier
for the controller/bus. This value is a dynamic ID assigned in
spmi_controller_alloc, and overriding it from the driver results in an
ida_free error "ida_free called for id=xx which is not allocated".

Convert to the device-managed version of spmi_controller_add() and
delete the unnecessary driver remove callback.

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 (mostly) ignored
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.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The Hisilicon 6421v600 SPMI driver is ready for mainstream.
So, move it from staging.
