usb: musb: Allow building in all the DMA code

Browse source 
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.

config MUSB_PIO_ONLY
bool 'Disable DMA (always use PIO)'
help
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.
All data is copied between memory and FIFO by the CPU.
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.
