[PATCH] powercap: idle_inject: Fix the comment about play_idle

[Frank Lee <frank@allwinnertech.com>]

From: Yangtao Li <tiny.windzz@gmail.com>

After commit 333cff6c963fbc ("powercap/drivers/idle_inject: Specify
idle state max latency"), we convert to use play_idle_precise() with
max allowed latency to specify the idle state.

Some function comments still use play_idle(), let's update it to
play_idle_precise().
