linux-gen: cpu: add configuration option to use static cpu frequency
Add 'system:cpu_hz_static' configuration option for using a static CPU
frequency value. When enabled, CPU frequency values returned by
odp_cpu_hz() and odp_cpu_hz_id() calls are read from the OS only once
during ODP initialization. Enabling this option removes system calls from
odp_cpu_hz() and odp_cpu_hz_id() implementations.
NOTE: This option should only be used on systems where CPU frequency
scaling is disabled.
