[PATCH] pc9800: merge std_resources.c back into setup.c 

std_resources.{c,h} was only split off due to pc9800 wanting to override it.
With it gone, it might as well be merged back in.  Doesn't change any code.
It was compiled and booted.

This time this also actually doesn't break compilation of any of the
subarches.  That's to say, any further.  I guess it might have been my .config
(my regular PC config, with just the subarch switched through menuconfig) or
O=, but only ELAN actually compiled.  Voyager and VISWS bombed out at the
final link and NUMAQ much sooner (with "physnode_map undeclared" during
compilation of numaq.c).
