IIUC, if it's "not available" the driver will still see the controller
regs, but it will be trying to control pins that are actually routed to
another device. That said, it should be the driver calling into
SoC-specific code to find out, rather than a global SATA-blocker (what
if a PCIe SATA card were used?).
