Maarten Lankhorst 66b68d2374 nouveau: Fix alignment requirements on src and dst addresses
commit ce806a3047 upstream.

Linear copy works by adding the offset to the buffer address,
which may end up not being 16-byte aligned.

Some tests I've written for prime_pcopy show that the engine
allows this correctly, so the restriction on lowest 4 bits of
address can be lifted safely.

The comments added were by envyas, I think because I used
a newer version.
