radeonfb: misc cleanup of engine and dst cache handling
Fix a couple of incomplete tests of the chip families in the engine init/reset code and proper initialization of the destination cache mode. The result should better match what the latest X radeon driver does. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: David S.
