t210: Apply A57 hardware issue workaround during cpu startup

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.
