Prarit Bhargava 785ee27881 cpufreq: intel_pstate: Fix limits->max_perf rounding error 
A rounding error was found in the calculation of limits->max_perf
in intel_pstate_set_policy(), which is used to calculate the max and min
pstate values in intel_pstate_get_min_max().  In that code,
limits->max_perf is truncated to 2 hex digits such that, for example,
0x169 was incorrectly calculated to 0x16 instead of 0x17.  This resulted in
the pstate being set one level too low.  This patch rounds the value of
limits->max_perf up instead of down so that the correct max pstate can
be reached.
