Currently R5 applications are handedoff immediately after they are loaded.
This feature is configurable in FSBL and now with this change, early handoff
is disabled by default. User can enable this feature again by defining
FSBL_EARLY_HANDOFF_EXCLUDE_VAL as 1.

Bootgen currently has no support for multiple loadable sections
in elfs. So a workaround is being implemented in PMUFW linker
script. All sections are forced to be loadable and dummy bytes
are added to fill the gaps. This change causes linker to throw
a warning about bss section being made PROGBITS.

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.

These are wrappers around IPI driver functions and are intended to
