powerpc: Don't preempt_disable() in show_cpuinfo()
commit 349524bc0da698ec77f2057cf4a4948eb6349265 upstream.
This causes warnings from cpufreq mutex code. This is also rather
unnecessary and ineffective. If we really want to prevent concurrent
unplug, we could take the unplug read lock but I don't see this being
critical.
Fixes: cd77b5ce208c ("powerpc/powernv/cpufreq: Fix the frequency read by /proc/cpuinfo")
