thermal: rockchip: optimize sensor auto accessing period

In less than 10 ms, the temperature of soc will arise 10 degree. 250 ms
is too big for soc tempeture control. Setting 2.5 ms will speed up
temperature accessing speed but introduce no more cpu's computing overhead.
We set AUTO_PERIOD_TIME and TSADCV3_AUTO_PERIOD_HT_TIME the same value,
because normal temperature update speed is also our consern in IPA.
