[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. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

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.
