astbmc/slot: Add _add_slot_info()

Currently slot_table_get_slot_info() scans the platform defined slot
table looking for a slot table entry that matches the device and adds
the relevant information to the struct pci_device. This patch splits
the searching and adding of the slot information into separate
functions so that we can allow the platform code to use a different
searching critera.
