Instead of taking the group/command separately, make the function
take a combined command ID. In many cases, this allows us to pass
an existing command ID (e.g. cmd.id), or introduce a new variable
for it, so that we don't use the command ID twice.

This way, we can also use LONG_GROUP implicitly, so we don't need
to spell that out for many commands.

Apart from mvm.h, fw/img.{c,h} changes and some copyright and
indentation updates, this was done with spatch:
