[PATCH] Fix AGP __setup warning + elsewhere

[John Levon]

drivers/char/agp/backend.c:322: warning: `agp_setup' defined but not used

Whilst __setup is allegedly obsolete, this usage at least is going to stay
around, and there are plenty of other places that currently have unnecessary
#ifdefs (any place that's worried about a few bytes of module size bloat can
still keep the ifdefs of course ...)

This just uses the same trick as module_init() to avoid the warning.

regards
john
