====================
devlink: Move devlink dev code to a separate file

This patchset is moving code from the file leftover.c to new file dev.c.
About 1.3K lines are moved by this patchset covering most of the devlink
dev object callbacks and functionality: reload, eswitch, info, flash and
selftest.
