[PATCH] remove constant_tsc reporting from /proc/cpuinfo' power flags

From: Joerg Roedel <joerg.roedel@amd.com>

This patch removes the reporting of the constant_tsc flag from the
"power management" field in /proc/cpuinfo. The NULL value there was
replaced by "" because the former would result in a printout of [8] if
the flag is set.
