drm/nv50: use custom i2c algo for dp auxch
This makes it easier to see how this is working, and lets us transfer the EDID in blocks of 16 bytes. The primary reason for this change is because debug logs are rather hard to read with the hundreds of single-byte auxch transactions that occur. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
