[ Upstream commit 0f33250760384e05c36466b0a2f92f3c6007ba92 ]

Below commit claims that atlantic NIC requires to reset the device on pm
op, and had set the deep to true for all suspend/resume functions.
commit 1809c30b6e5a ("net: atlantic: always deep reset on pm op, fixing up my null deref regression")
So, we could remove deep parameter on suspend/resume functions without
any functional change.

Fixes: 1809c30b6e5a ("net: atlantic: always deep reset on pm op, fixing up my null deref regression")
