You're right ... _potentially_ useful, which is the same standard used
in most of the other cases.  The "X86_PC" is debris from an early version
of this patch, which limited the code to cases where it was known to work.
The X86_PC hardware standard does standardize on this particular RTC, but
non-PC platforms can use it too.

I still need to resubmit the patch, for X86_PC, which defines the platform
device in the (common) case where PNPACPI isn't defined.  Other X86 boards
would need something similar, based on what chips are wired to the CPU.
