soc/tegra: fix permission of forced_idle_duration_us
"nvidia-bug-report-tegra.sh" tries to read all files with
read permission from path "/sys/kernel/debug/*cpuidle*/".
Permission for "forced_idle_duration_us" node is wrongly
set to read also but only write to this node is supported.
So, reading it causes permission error. Changing permission
to only write for root user to fix the error.
