Display team introduces new refresh rate residency in kernel. Current display data provider is polling data from state sysfs. To reduce CPU loading and improve efficiency, we should get rid of polling data provider and create new data provider to read data from time_in_state sysfs in PowerStatsHAL. Bug: 316260832 Test: vts-tradefed run vts -m VtsHalPowerStatsTargetTest Change-Id: I4d9886f13207e41f13defd89ea2c19614918a570 Signed-off-by: Darren Hsu <darrenhsu@google.com>
