Timo Alho af51c25fb5 firmware: tegra: Use in-band messages for firmware version query
Add support for a new MRQ, that uses in-band messaging instead of IOVA
buffer, to retrieve the firmware version 'tag' during boot. If an
older firmware is used, that does not support the new MRQ, fall back
to the earlier implementation.
