msm: cpufreq: boost freq of online cpu(s) to max on resume

Resume events cause several tasks to initiate such as WiFi connect,
data sync, etc. that require cpu cycles. Instead of waiting for the cpu
governor to increase the cpu frequency which occur after an unpleasant delay,
start at the max frequency and the cpu governor will scale the frequency
back as soon as possible. This shouldn't have any noticeable impact on battery
life.
