According to version 20250508 of the privileged specification,
mhpmeventn is 64 bits in size and mhpmeventnh is only ever used
when XLEN == 32 and accesses the top 32 bits of the 64-bit
mhpmeventn registers. Combine the two arrays of target_ulong
mhpmeventh[] and mhpmevent[] to a single array of uint64_t.
This also allows for some minor code simplification where branches
handling either mhpmeventh[] or mhpmevent[] could be combined.
