Subject: [PATCH 4.9 100/153] usb: musb: da8xx: Remove CPPI 3.0 quirk and methods

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexandre Bailon <abailon@...libre.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.

Fixes: f8e9f34f80a2 ("usb: musb: Fix up DMA related macros")
Fixes: 7f6283ed6fe8 ("usb: musb: Set up function pointers for DMA")
