linux-gen: sysinfo: use cpufreq for max freq by default
Usually, maximum CPU frequency is found from a cpufreq file. Read that file first, if it's not found use cpuinfo instead. If max freq cannot be found, use hard coded value and print a warning.

example: sysinfo: application to print system information
Add new application that simply queries and prints out various system information which is available through ODP APIs. This can be useful e.g. when examining HW or ODP implementation capabilities, when debugging other ODP applications, etc.
