cpufreq: qcom-hw: enable boost support 



At least on sdm850, the 2956800 khz is detected as a boost frequency in
function qcom_cpufreq_hw_read_lut().  Let's enable boost support by
calling cpufreq_enable_boost_support(), so that we can get the boost
frequency by switching it on via 'boost' sysfs entry like below.

 $ echo 1 > /sys/devices/system/cpu/cpufreq/boost
