Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to remove legacy power management
callbacks and invocation of PCI helper functions, from tulip ethernet drivers.

With legacy PM, drivers themselves are responsible for handling the device's
power states. And they do this with the help of PCI helper functions like
pci_enable/disable_device(), pci_set/restore_state(), pci_set_powr_state(), etc.
which is not recommended.

In generic PM, all the required tasks are handled by PCI core and drivers need
to perform device-specific operations only.

All patches are compile-tested only.
