api: use MHz for all clocks and show plimit

plimit value is reported in mW like the power, or % on Windows x86 (via nvapi)

+ the monitor thread will no more report 0W if the device doesnt support it

also upgrade nvml and sample php api.

some more changes may come in this temporary API 1.9 (for the final 2.0)
