pcidev: Move pci_dev_find() from internal to canonical place

Also rename to `pcidev_find()` in fitting with pcidev.c helpers.

Tested: ```sudo ./flashrom -p internal -r /tmp/bios
<snip>
Found Programmer flash chip "Opaque flash chip" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000.
Reading flash... done.
```
