Add and use #defines for PCI device classes

This patch adds and uses #defines for PCI device classes and subclases,
using a new pci_config_set_class() function, similar to the recently
added pci_config_set_vendor_id() and pci_config_set_device_id().

Change since v1: fixed compilation of hw/sun4u.c
