[RFC v2 3/6] crypto: qat - address recursive dependency when fw signing is enabled

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>
We're going to add firmware module signing support, but when we do
this we end up with the following recursive dependency. Fix this by
just depending on FW_LOADER, which is typically always enabled
anyway. We do this as a compromise for now as FW_LOADER is only
selectable when EXPERT is enabled and the recursive dependency issue
below is actually real and valid, its proper fix however requires
a bit of work.
This technically means this change is likely welcomed for other
parts of the kernel but this is really only needed for now here.
