The only user of _alpha_iobase_query (defined lnx_axp.c:171) was
hw/xfree86/os-support/bus/axpPci.c, through _iobase (defined
lnx_axp.c:136).

I don't have any hardware capable of testing sparse support, but it's
either already broken (so killing this code won't hurt anything) or
it's working (so killing this unused code won't hurt anything).
So...
