ENGR00332496 Revert "ENGR00313729 usb: class: acm: use nonbufferable memory for rx dma buffer"
Since we already use non-bufferable dma memory for all usb host dma memory
allocations which can cover all class drivers, so revert this commmit.
This reverts commit e314064d431d32a5a81da6681f57cdb3c20cad5b.
