[POWERPC] PMU: Remove dead code
Some code in via-pmu.c is never compiled because of "compile options" within the file. Remove the code completely. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
