History
Vaibhav Gupta a4ba7df57e fbdev: savagefb: use generic power management 
Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.

Switch to the new generic framework by updating function signatures and
define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove
unnecessary calls to the PCI Helper functions along with the legacy
.suspend & .resume bindings.

Now,
- savagefb_suspend() had a "pm_message_t" type parameter as per legacy
  PCI PM framework that got deprecated in generic.
- Rename the callback as savagefb_suspend_late() and preserve the
  parameter.
- Define 3 new callbacks as:
        * savagefb_suspend()
        * savagefb_freeze()
        * savagefb_hibernate()
  which in turn call savagefb_suspend_late() by passing appropriate value
  for "pm_message_t" type parameter.
- Bind the callbacks in "struct dev_pm_ops" type variable
  "savagefb_pm_ops".
