Input: iforce - use DMA-safe buffores for USB transfers

USB transport has to use cache line-aligned buffers for transfers to avoid
DMA issues; serio doe snot have such restrictions. Let's move "data_in"
buffer from main driver structure into transport modules and make sure USB
requirements are respected.
