tegra124: fix the dangerous VPR write order

Currently we put the VPR write code just right before the AVP is going
to freeze. We have no idea does the write operation successful or not
before halting the AVP. And the power_on_main_cpu should be the last step
of that. So we make a fix to change the order.

BUG=none
BRANCH=none
TEST=LP0 suspend stress test and check the VPR is correct;
     LP0 suspend stress test with video playback
