arm/acpi: fix PCI _PRT definition
The address field in each _PRT mapping package should be constructed
with high word for device# and low word for function#, so it is wrong
to use bus_no as the high word. The existing code adds a bunch useless
entries with device #s above 31. Enumerate all possible slots
(i.e. PCI_SLOT_MAX) instead.
