PMUFW: Core: Clear DONT_SLEEP bit during initialization

Browse source 
DONT_SLEEP bit in PMU GLobal control register, if set,  wakes up the
microblaze from sleep state. This makes the "sleep" instruction
ineffective by making the MB to toggle between sleep and wake states
in the core loop. So this bit is cleared to prevent such a situation
and ensure that MB wakes up only in case of an interrupt event.
