Currently powertop uses the /etc/boardname to retrive the boardname
as well as set the global_fixed_parameters and global_power_override
global variables. /etc/boardname is a meego specific feature and not
present in Android. This patch enables powertop to get the board name
using getprop system call in case of Android devices and creates a
file for saved parameters with boardname extension at /data/local/powertop
directory
