The start variables made the code clearer when we had to access
cb->args[0] directly, as the name args doesn't explain much.
Now that we use a structure to hold state this seems no longer
needed.

Create a dump context structure instead of using cb->args
as an unsigned long array. This is a pure conversion which
is intended to be as much of a noop as possible.
Subsequent changes will use this to simplify the code.
The two non-trivial parts are:
- devlink_nl_cmd_health_reporter_dump_get_dumpit() checks args[0]
to see if devlink_fmsg_dumpit() has already been called (whether
this is the first msg), but doesn't use the exact value, so we
can drop the local variable there already
- devlink_nl_cmd_region_read_dumpit() uses args[0] for address
but we'll use args[1] now, shouldn't matter

Move out the netlink glue into a separate file.
Leave the ops in the old file because we'd have to export a ton
of functions. Going forward we should switch to split ops which
will let us to put the new ops in the netlink.c file.
Pure code move, no functional changes.

Move core code into a separate file. It's spread around the main
file which makes refactoring and figuring out how devlink works
harder.
Move the xarray, all the most core devlink instance code out like
locking, ref counting, alloc, register, etc. Leave port stuff in
leftover.c, if we want to move port code it'd probably be to its
own file.

To make the upcoming change a pure(er?) code move rename
devlink_netdevice_event -> devlink_port_netdevice_event.
This makes it clear that it only touches ports and doesn't
belong cleanly in the core.

The devlink code is hard to navigate with 13kLoC in one file.
I really like the way Michal split the ethtool into per-command
files and core. It'd probably be too much to split it all up,
but we can at least separate the core parts out of the per-cmd
implementations and put it in a directory so that new commands
can be separate files.
Move the code, subsequent commit will do a partial split.
