libpayload/libpci: Introduce device class attribute in pci_dev
The device class is read at different places and it is read from the
hardware directly. Therefore, and in preparation to CB:46416, introduce
the device class attribute in the pci_dev struct. With this, there is
only one interaction with the hardware and it's also more user friendly.
