The added HAS_IOPORT dependency might not actually be necessary as Geert
points out, but the driver is also only used on one architecture. Sparc
is also a special case here since it converts port numbers into virtual
addresses rather than having them mapped into a particular part of the
__iomem address space, so the difference is actually not important here.
Add a dependency on sparc, but allow compile-testing otherwise, to
make this clearer without anyone having to spend much time modernizing
the driver beyond that.

If you say Y here you will get support for the TI
BQ4802 RTC chip.

I'd rather just add a line "depends on SPARC || COMPILE_TEST",
which is easier to parse.
