Subject: usb: musb: da8xx: Remove CPPI 3.0 quirk and methods

From: Alexandre Bailon <abailon@baylibre.com>

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.
