[PATCH] powerpc/powernv: Fix IMC_MAX_PMU macro

[Anju T Sudhakar]

IMC_MAX_PMU is used for static storage (per_nest_pmu_arr) which holds
nest pmu information. Current value for the macro is 32 based on
the initial number of nest pmu units supported by the nest microcode.
Currently 29 nest units are enabled based on the system configuration.
But going forward, microcode could support more nest units (max of 64
nest units). Hence fix the value for the macro.
