Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to remove legacy power management callbacks
from ide drivers.

The suspend() and resume() callbacks operations are still invoking
pci_save/restore_state(), pci_set_power_state(), pci_enable/disable_state(),
etc. and handling the power management themselves, which is not recommended.

The conversion requires the removal of the those function calls and change the
callback definition accordingly and make use of dev_pm_ops structure.

All patches are compile-tested only.

v3:
    - Modpost error for undefined reference by Kbuild in v1.
    - Another approach to disable PM in drivers/ide/triflex.c suggested by
      Bjorn Helgaas in v2.

Test tools:
    - Compiler: gcc (GCC) 10.1.0
    - allmodconfig build: make -j$(nproc) W=1 all
