Swapnil Sapkal 2a85bbaed0 perf header: Replace hardcoded max cpus by MAX_NR_CPUS 
cpumask and cpulist from cpu-domain header have hardcoded max_cpus value
of 1024.

Current systems have more cpus than this value. Replace it with
MAX_NR_CPUS.

Also define a macro to represent domain name length.

Fixes: d40c68a49f ("perf header: Support CPU DOMAIN relation info")
