soundwire: bus: Update kernel doc for no_pm functions

Browse Source 
The kernel doc should really have been updated when the no_pm versions
of the sdw_write/read functions were exported in commits:

commit 167790abb9 ("soundwire: export sdw_write/read_no_pm functions")
commit 62dc9f3f2f ("soundwire: bus: export sdw_nwrite_no_pm and
                      sdw_nread_no_pm functions")

Add the missing kernel doc.
