Subject: [PATCH] thermal: update CPU/GPU throttling policy to optimize perf

1. GPU 202Mhz thermal throttling is too aggressive and cause frame missing. So, adjust the hardlimit and cdev_ceiling to improve perf.

2. Set the cdev_ceiling for CPU to avoid the abnormal throttling request when ODPM has issue.

Bug: 234998975
Test: Confirm fps drop for pip test
