[dts] [PATCH] modify the initialization of core list on linux

[yongjie]

Change the order to obtain socket info by "lscpu -p"
Output of "lscpu -p" on Ubuntu14.04:
# The following is the parsable format, which can be fed to other
# programs. Each different item in every column has an unique ID
# starting from zero.
