tprof_lock is not a spin mutex. use mutex_{enter,exit}(). oops

Explicitly disable overflow interrupts before enabling the cycle counter.

PMCR_EL0.LC should be set. ARM deprecates use of PMCR_EL0.LC=0

Even if an overflow interrupt is occured for a counter outside tprof management,
the bit of onverflow status register must be cleared to prevent an interrupt storm.
