Zide Chen 5f2c303a7e acrn-config: dump CPU info from /sys/devices/system/cpu/possible ...

/proc/cpuinfo represents online CPUs only, and the number of CPUs is
limited by the 'maxcpus' option.

/sys/devices/system/cpu/possible is a better option for our purpose
since it represents the possible CPUs that can ever be available in the
system, including the offline CPUs. And it's not limited by 'maxcpus'.

Though the Linux command line parameter nr_cpus and possible_cpus still
have impact on /sys/devices/system/cpu/possible.
