Commit Message

Cabiddu, Giovanni May 17, 2022, 2:10 p.m. UTC 
The function adf_sriov_prepare_restart() is used in adf_sriov.c to stop
and shutdown a device preserving its configuration.

Since this function will be re-used by the logic that allows to
reconfigure the device through sysfs, move it to adf_init.c and rename
it as adf_dev_shutdown_cache_cfg();
