You need to grep for "microcode", not "firmware". On my system I see:

% dmesg |grep -i microcode
[   18.890581] [drm] Loading RV730 Microcode

That doesn't look too different from my dmesg output. Your last line is almost
identical to my system.

However, if Bruce is correct, you'll have to try the proprietary drivers (at
least for 3D support, I suspect it'll work fine otherwise).
