arm64: dtsi: rk3399: optimize ipa parameters

Big cores' power consumption is as much as 8 times of little cores'.
Eas tends to bring tasks to big cores to assure the performance, and
this will make the temperature of soc out of control. To resolve this
issue, we set the power request weight of both little cores and gpu is
10 times of big cores, when temperature control occurs. Meanwhile, we
decrease passive polling interval to make temperature control more
accurate.
