sis-agp: convert to generic power management

Convert sis-agp from legacy PCI power management to the generic power
management framework.

Previously, sis-agp used legacy PCI power management, and agp_sis_suspend()
and agp_sis_resume() were responsible for both device-specific things and
generic PCI things:

agp_sis_suspend
pci_save_state(pdev) <-- generic PCI
pci_set_power_state(pdev, pci_choose_state(pdev, state)) <-- generic PCI

agp_sis_resume
pci_set_power_state(pdev, PCI_D0) <-- generic PCI
pci_restore_state(pdev) <-- generic PCI
sis_driver.configure() <-- device-specific

With generic power management, the PCI bus PM methods do the generic PCI
things, and the driver needs only the device-specific part, i.e.,

suspend_devices_and_enter
dpm_suspend_start(PMSG_SUSPEND)
pci_pm_suspend # PCI bus .suspend() method
agp_sis_suspend <-- not needed at all; removed
suspend_enter
dpm_suspend_noirq(PMSG_SUSPEND)
pci_pm_suspend_noirq # PCI bus .suspend_noirq() method
pci_save_state <-- generic PCI
pci_prepare_to_sleep <-- generic PCI
pci_set_power_state
...
dpm_resume_end(PMSG_RESUME)
pci_pm_resume # PCI bus .resume() method
pci_restore_standard_config
pci_set_power_state(PCI_D0) <-- generic PCI
pci_restore_state <-- generic PCI
agp_sis_resume # dev->driver->pm->resume
sis_driver.configure() <-- device-specific

Pull drm updates from Dave Airlie:
"This is the main drm pull request for 4.14 merge window.

I'm sending this early, as my continuing journey into fatherhood is
occurring really soon now, I'm going to be mostly useless for the next
couple of weeks, though I may be able to read email, I doubt I'll be
doing much patch applications or git sending. If anything urgent pops
up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards
you.

Outside drm changes:

Some rcar-du updates that touch the V4L tree, all acks should be in
place. It adds one export to the radix tree code for new i915 use
case. There are some minor AGP cleanups (don't see that too often).
