Subject: [PATCH 3/3] Char: sx, fix non-PCI build

sx, fix non-PCI build

When CONFIG_PCI is not defined (i.e. PCI bus is disabled), the sx
driver fails to link, since some pci functions are not available. Fix this
behaviour to be able to compile this driver on machines with no PCI bus (but
with ISA bus support).
