- Assume control of portdrv-related features only when portdrv is enabled,
since we can't use them without portdrv (Kuppuswamy Sathyanarayanan)
- Tidy _OSC control bit checking (Kuppuswamy Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
