PCI/PM: Call .bridge_d3() hook only if non-NULL
26ad34d510a8 ("PCI / ACPI: Whitelist D3 for more PCIe hotplug ports") added
the struct pci_platform_pm_ops.bridge_d3() function pointer and
platform_pci_bridge_d3() to use it.
The .bridge_d3() op is implemented by acpi_pci_platform_pm, but not by
mid_pci_platform_pm. We don't expect platform_pci_bridge_d3() to be called
on Intel MID platforms, but nothing in the code itself would prevent that.
Check the .bridge_d3() pointer for NULL before calling it.
Fixes: 26ad34d510a8 ("PCI / ACPI: Whitelist D3 for more PCIe hotplug ports")
