One nit-pick below, otherwise

Thinking more about this change I would probably add a comment on top of
sst_alloc_drv_context() call in sst_acpi.c to tell that in this case the
driver handles PCI IDs in ACPI and we are using only device ID part.
(If real ACPI ID appears, the kstrtouint() returns error, so we are fine
 with the change)

So, summarize above and add a comment.
