usb: musb: Allow building in all the DMA code
With recent changes to MUSB code, we can now now get rid of the Kconfig choise for the DMA code and allow building in any of the desired DMA code. This makes life easier for distros. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

Unfortunately, only one option can be enabled here. Ideally one

should be able to build all these drivers into one kernel to

allow using DMA on multiplatform kernels.

DMA controllers are ignored.

Do not choose this unless DMA support for your SOC or board

is unavailable (or unstable). When DMA is enabled at compile time,
|

you can still disable it at run time using the "use_dma=n" module

parameter.
