[PATCH v5 1/4] bus/pci: fix registration of PCI device

[Shani Peretz]

When registering a new PCI device, the device->name field stored
the user-provided string from devargs (e.g., "08:00.0" or "0000:08:00.0").
This approach led to inconsistencies when registering new devices.

This patch fix this issue by saving the parsed PCI in device->name,
so when a new PCI device is registering the name displayed in the device
list will be the parsed version.

Fixes: 23eaa9059ec2 ("bus/pci: use given name as generic name")

It's way simpler.
