Remove useless get_driver()/put_driver() calls

As part of the removal of get_driver()/put_driver(), this patch
(as1512) gets rid of various useless and unnecessary calls in several
drivers.  In some cases it may be desirable to pin the driver by
calling try_module_get(), but that can be done later.
