Convert clock unit 10KHz to KHz as the data sturct defined.
e.g.
struct pp_clock_with_latency {
uint32_t clocks_in_khz;
uint32_t latency_in_us;
};
Meanwhile revert the same conversion in display side.

As hw required, soc clock must large than mclk, So we set max soc
clock to OD Max Memory clk.
But on workstation, vbios do not support OD feature, the OD max memory
clock is equal to 0. In this case, driver can support underclocking.
and set od max memory clock to the value in highest memory dpm level.
So the od max memory clock should be less than highest soc clock.
and driver should not change the soc clock.

and can configure the clock/voltage by writing pp_od_clk_voltage
for example:
echo "s 0 900 820">pp_od_clk_voltage to change the sclk/vddc
to 900MHz and 820 mV in dpm level0.
echo "r" to change the clk/voltage to default value.
echo "c">pp_od_clk_voltage

Currently smu only calculate average gpu power in real time.
for vddc/vddci/max power,
User need to set start time and end time, firmware can calculate
the average vddc/vddci/max power. but the type of return values
is not unified. For Vi, return type is uint.
For vega, return type is float.
so this struct can't be suitable for all asics.
