pci: fix errant data types and corresponding access functions
In a couple of places, unsigned int and pci_config_*_dword were being used when u16 and _word should be used. Unsigned int was also being used in a couple of places that should be pci_addr_t. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
