I think I can break this patch into one commit per driver. The reason that
all updates got into one single patch is that I made
ata_pci_device_suspend/resume() static and exported just the
ata_pci_device_pm_ops variable. Thus, all the driver using .suspend/.resume()
had to be updated in a single patch.

First I will make changes in drivers/ata/libata-core.c, but won't make any
function static. Thus, each driver can be updated in independent commits
without breaking anything. And then in the last commit, I can hide the
unnecessary .suspend()/.resume() callbacks. This will create patch-series of 55
or 56 patches.

Will this approach work?
