Revert "x86: CPU: Fix up "cpu MHz" in /proc/cpuinfo"
This reverts commit 941f5f0f . Sadly, it turns out that we really can't just do the cross-CPU IPI to all CPU's to get their proper frequencies, because it's much too expensive on systems with lots of cores. So we'll have to revert this for now, and revisit it using a smarter model (probably doing one system-wide IPI at open time, and doing all the frequency calculations in parallel).
