Define custom stage_entry to apply workaround for A57 hardware issue for power on reset. It is observed that BTB contains stale data after power on reset. This could lead to unexpected branching and crashes at random intervals during the boot flow. Thus, invalidate the BTB immediately after power on reset. BUG=chrome-os-partner:41877 BRANCH=None TEST=Compiles successfully and reboot test does not crash in firmware for 10K iterations.
