Read PCI devices through devicetree instead of scanning PCI bus in kernel

[duanyu-yu]

See:

• Update of PCI scanning process in fdt loader#425

[duanyu-yu]

The PCI bus is now scanned in the loader instead of in the kernel. The related changes in the loader and hermit-rs can be found at https://github.com/duanyu-yu/hermit-rs/tree/pci and https://github.com/duanyu-yu/hermit-loader/tree/pci.
