pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.

Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().

Remove unused rtsx_read_pci_cfg_byte() function.

You only need this one sentance here for the changelog for this patch.
And the subject line makes no sense.

Please fix up and resend.
