[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.

-config DEBUG_IOREMAP
- bool "Enable ioremap() debugging"
- depends on DEBUG_KERNEL && 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.
