Subject: L2CR patch

Enclosed is a patch that replace the _set_L2CR function in the kernel by
a new version that is safer (does the appropriate flushing etc... when
enabling the cache).
See comments about usage. I also added an "l2cr=" kernel command-line
option that will be used by future versions of BootX to give the kernel a
correct l2cr setting for people with G3 upgrade cards. BootX application
will be able to "capture" the l2cr value set by the upgrade card software
and put it in a pref for use when booting.
The _set_L2CR was provided by Terry Greeniaus from PowerLogix, so thanks
to PowerLogix for the support !
