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.
