The SDMA IP is independent from the GFX IP, so it is technically
wrong to program it based on the GFX level.
This patch changes the RADV SDMA code to use SDMA IP versions
where possible.

The vast majority of AMD GPUs (except the very first GCN) have
the same SDMA packet format, so let's just call it SDMA instead
of CIK_SDMA.
(And leave the oldest GPUs with SI_SDMA as they are now.)

This naming is more accurate and closer to the HW.

When the pitch or slice pitch isn't properly aligned,
the SDMA HW is unable to copy between tiled images and buffers.
To work around this, we process the image chunk by chunk,
copying the data to a temporary buffer which uses supported
pitches, and then copy it to the intended destination.
The implementation assumes that at least one pixel row of the
image will fit into the temporary buffer, and will try to copy
as many rows at once as possible. Sadly, this still results in
a lot of packets being generated for large images.
A possibe future improvement is to copy the image slice by slice
when only the slice pitch is misaligned. However, that is out
of scope for this commit.

Previously, RADV only had a simple implementation of
image to buffer copies using the SDMA for the PRIME copy.
This commit replaces that with a full-featured implementation
that includes buffer to image and image to buffer copies and
removes the assumptions that the PRIME copy had, as well as
adds new helper functions which will be shared with other copy
functions in upcoming commits.
Unaligned buffer/image copies require a workaround, which
will be implemented by a future commit.
