[PARISC] Remove obsolete CONFIG_DEBUG_IOREMAP

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.

-         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.
