spmi: rename spmi device lookup helper

Rename the SPMI device helper which is used to lookup a device from its
OF node as spmi_find_device_by_of_node() so that it reflects the
implementation and matches how other helpers like this are named.

This will specifically make it more clear that this is a lookup function
which returns a reference counted structure.
