drm/msm/a2xx: stop over-complaining about the legacy firmware

Browse Source 
If the rootfs have a legacy A200 firmware, currently the driver will
complain each time the hw is reinited (which can happen a lot). E.g.
with GL testsuite the hw is reinited after each test, spamming the
console.

Make sure that the message is printed only once: when we detect the
firmware that doesn't support protection.
