The IRQ handler was passed a pointer to a struct dma_controller, but the
argument was then casted to a pointer to a struct musb_dma_controller.

The implementation of the Inventra IP in some of the Ingenic JZ47xx SoCs
does not use a separate IRQ line for DMA transfers.
Allow these SoCs to be supported by adding a flag 'dma_share_usb_irq'
in the struct musb. If set, no extra IRQ line is required, and the musb
glue will need to call the API function musbhs_dma_controller_irq()
within its interrupt handler.

It has to be disabled at init time, as we cannot guarantee that a gadget

It seems the patch has a few different types of cleanup, coding style,
indentation, data structure change, variable name change...
