Subject: [PATCH 2/4] cpufreq: Update boost flag while initializing freq table from OPPs

From: Bartlomiej Zolnierkiewicz <b.zolnierkie@...sung.com>

cpufreq table entries for OPPs with turbo modes enabled, should be
marked with CPUFREQ_BOOST_FREQ flag. This ensures that these states are
only used while operating in boost or turbo mode.
