Subject: [PATCH] dwc_otg: Declare DMA capability with HCD_DMA flag
Following [1], USB controllers have to declare DMA capabilities in
order for them to be used by adding the HCD_DMA flag to their hc_driver
struct.
[1] 7b81cb6bddd2 ("usb: add a HCD_DMA flag instead of guestimating DMA capabilities")
