In some case, the pll rate will be change to get a target
rate for it's child. we want set the pll rate closest to
the max pll rate. However, It's not all the rate can get
a set of legal paramters to config the pll. So when this
case happen, we try a lower rate as the target pll rate.

The WARNING is due to the driver expecting 'gpu_ts' (gpu_timestamp) from the FW
to be monotonically increasing, but here "after waking up, 'gpu_ts' is smaller than before sleep."
'gpu_ts' comes from the GPU's input signal CNTVALUEB.
CNTVALUEB comes from the 'stimer' timer.
derrick.huang@rock-chips.com confirmed that this timer loses power during sleep,
and its count is reset when the system wakes up.
This causes "'gpu_ts' to be smaller after waking up than before sleep."
derrick.huang also mentioned that "for RK3588, it is not possible
to make 'stimer' not lose power in the product."
Here, we are temporarily disabling this WARNING.
It is speculated that sleep-wake cycles
might lead to certain profile features of the GPU not functioning correctly.
Further testing will be conducted to check for other potential issues.
