libhwc2.1: wait for peak refresh rate via sysfs node
Refresh_rate sysfs node will signal after the mipi commands for refresh
rate have been sent out, which means the next frame scanned out by next
TE will be displayed at the new refresh rate. Note there are cases panel
needs more time to reach the new refresh rate. Not a concern at this
time (neither lhbm nor compensation).
