====================
sh_eth: massage PM code

   Here's a set of 2 patches against DaveM's 'net-next.git' repo. We're adding
the support for suspend/hibernation as well as somewhat changing the existing
code. There are still MDIO-related issue with suspend (kernel exception), we've
been working on it and shall address it with a separate patch...
