usb: musb: use DMA mode 1 whenever possible
Do not rely on any hints from gadget drivers and use DMA mode 1
whenever we expect data of at least the endpoint's packet size and
have not yet received a short packet.
The last packet if short is always transferred using DMA mode 0.
This patch fixes USB throughput issues in mass storage mode for
host to device transfers.
