Xiaoguang Wu 06781b37e9 DM USB: dynamically allocate block count for struct usb_xfer ...

The block count of the struct usb_xfer is hard coded by the macro
USB_MAX_XFER_BLOCKS (1024), it wastes memory if 1024 blocks are
allocated for low speed transfer such as control transfer or interrupt
transfer. This patch introduces a new method to allocate different
number of blocks according to different endpoint type.
