rbcfg: Implement CPU frequency control
This patch implements CPU frequency control as found on several
routerboard devices.
Supported SoCs:
- QCA953X
- AR9344
Tested on hAP lite and mAP lite (QCA953x): steps of 50MHz
Tested on LHG 5 (AR9344): steps of 50MHz
On unsupported hardware, this patch is a NOP: it will not alter the
new field.
"rbcfg help" will display an empty "cpu_freq" help listing.
"rbcfg show" will not show the cpu_freq field.
"rbcfg set/get cpu_freq" will return an error code.
