4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexandre Bailon <abailon@xxxxxxxxxxxx>
commit a994ce2d7e66008381a0b184c73be9ae9b72eb5c upstream.
DA8xx driver is registering and using the CPPI 3.0 DMA controller but
actually, the DA8xx has a CPPI 4.1 DMA controller.
Remove the CPPI 3.0 quirk and methods.
Fixes: f8e9f34f80a2 ("usb: musb: Fix up DMA related macros")
Fixes: 7f6283ed6fe8 ("usb: musb: Set up function pointers for DMA")
