net: atlantic: always deep reset on pm op, fixing up my null deref regression

The impact of this regression is the same for resume that I saw on
thaw: the kernel hangs and nothing except SysRq rebooting can be done.

Fixes regression in commit cbe6c3a ("net: atlantic: invert deep
par in pm functions, preventing null derefs"), where I disabled deep
pm resets in suspend and resume, trying to make sense of the
atl_resume_common() deep parameter in the first place.

It turns out, that atlantic always has to deep reset on pm
operations. Even though I expected that and tested resume, I screwed
up by kexec-rebooting into an unpatched kernel, thus missing the
breakage.

This fixup obsoletes the deep parameter of atl_resume_common, but I
leave the cleanup for the maintainers to post to mainline.

Suspend and hibernation were successfully tested by the reporters.
