ata: ftide010: Add a quirk for SQ201
The DMA is broken on this specific device for some unknown reason (probably badly designed or plain broken interface electronics) and will only work with PIO. Other users of the same hardware does not have this problem. Add a specific quirk so that this Gemini device gets DMA turned off. Also fix up some code around passing the port information around in probe while we're at it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
