[PARISC] Remove obsolete CONFIG_DEBUG_IOREMAP

Browse source 
Remove CONFIG_DEBUG_IOREMAP, it's now obsolete and won't work anyway.
Remove it from lib/KConfig since it was only available on parisc.

help
Enabling this option will cause the kernel to distinguish between
ioremapped and physical addresses. It will print a backtrace (at
most one every 10 seconds), hopefully allowing you to see which
drivers need work. Fixing all these problems is a prerequisite
for turning on USE_HPPA_IOREMAP. The warnings are harmless;
the kernel has enough information to fix the broken drivers
automatically, but we'd like to make it more efficient by not
having to do that.
