platform: tegra: rtcpu: Fix reboot debugfs

currently the reboot debugfs resets the RTCPU but
fails to restart it successfully.
So once reboot test is run, RTCPU is off, and no
other test is able to run.

This change fixes it by calling rtcpu start and
stop APIs, which perform correct steps to restart
rtcpu.
