x86/platform/intel-mid: Retrofit pci_platform_pm_ops ->get_state hook

Commit cc7cc02bada8 ("PCI: Query platform firmware for device power
state") augmented struct pci_platform_pm_ops with a ->get_state hook and
implemented it for acpi_pci_platform_pm, the only pci_platform_pm_ops
existing till v4.7.

However v4.8 introduced another pci_platform_pm_ops for Intel Mobile
Internet Devices with commit 5823d0893ec2 ("x86/platform/intel-mid: Add
Power Management Unit driver").  It is missing the ->get_state hook,
which is fatal since pci_set_platform_pm() enforces its presence.  Andy
Shevchenko reports that without the present commit, such a device
"crashes without even a character printed out on serial console and
reboots (since watchdog)".

Retrofit mid_pci_platform_pm with the missing callback to fix the
breakage.
