msm: cpufreq: Configure WQ for higer priority

When the workqueue runs at a lower priority, it gets starved by higher
priority threads. Bump the WQ priority to high to ensure cpufreq work
queue gets a fair scheduling chance

msm: spm: set vdd directly for current cpu

In cases where a cpu is setting vdd for itself we need not
call msm_spm_smp_set_vdd through smp_call_function_single.

Without this change when CPU calls for itself when interrupts
are disabled we get following warning
