Commit d9ea21a779278da06d0cbe989594bf542ed213d7 ("usb: host: make
USB_ARCH_HAS_?HCI obsolete") allowed to enable USB on platforms with
NO_DMA=y, and exposed several input and media USB drivers that just select
USB if USB_ARCH_HAS_HCD, without checking HAS_DMA.
Fix the former by making USB depend on HAS_DMA.
To fix the latter, instead of adding lots of "depends on HAS_DMA", make
those drivers depend on USB, instead of depending on USB_ARCH_HAS_HCD and
selecting USB. Drivers for other busses (e.g. MOUSE_SYNAPTICS_I2C) already
handle this in a similar way.
