intel/device: rename gen_get_device_info

Rename the original device info initialization routine so callers
don't mistakenly call the wrong one:

  gen_get_device_info_from_fd:

      Queries kernel for full device info, including topology
      details.

  gen_get_device_info_from_pci_id:

      Partially initializes device info based on PCI ID lookup, when
      the kernel is not available.
