ppc/xive2: Fix integer overflow warning in xive2_redistribute()
Coverity reported an integer overflow warning in xive2_redistribute()
where the code does a left shift operation "0xffffffff << crowd". Fix the
warning by using a 64 byte integer type. Also refactor the calculation
into dedicated routines.
Resolves: Coverity CID 1612608
Fixes: 555e446019f5 ("ppc/xive2: Support redistribution of group interrupts")
