PCI: Add PCI_DEVICE_DATA() macro to fully describe device ID entry
There are a lot of examples in the kernel where PCI_VDEVICE() is used and
still looks not so convenient due to additional driver_data field attached.
Introduce PCI_DEVICE_DATA() macro to fully describe device ID entry in
shortest possible form. For example,
before:
{ PCI_VDEVICE(INTEL, PCI_DEVICE_ID_INTEL_MRFLD),
(kernel_ulong_t) &dwc3_pci_mrfld_properties, },
after:
{ PCI_DEVICE_DATA(INTEL, MRFLD, &dwc3_pci_mrfld_properties) },
Drivers can be converted later on in independent way.
While here, remove the unused macro with the same name from Ralink wireless
driver.
