PCI: Set supported_speeds in set_pcie_port_type()

sparc64 and powerpc create PCI devices from the device tree in
of_create_pci_dev(), which calls set_pcie_port_type() but not
pci_setup_device(). Since d2bd39c0456b, supported_speeds is only set in
pci_setup_device(), so it stays 0 for these devices.

pcie_get_speed_cap() then returns PCI_SPEED_UNKNOWN, the sysfs
'max_link_speed' attribute reads "Unknown", and the failed link retraining
quirk passes PCI_SPEED_UNKNOWN to pcie_set_target_speed(), which warns on a
SPARC T7-1:

  WARNING: drivers/pci/pcie/bwctrl.c:125 at pcie_set_target_speed+0x284/0x2e0

Set supported_speeds in set_pcie_port_type(), which all three paths call.
