nouveau: Fix alignment requirements on src and dst addresses
commit ce806a30470bcd846d148bf39d46de3ad7748228 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.
