[U-Boot] [PATCH] usb: ohci: change the NUM_EDs from 8 to 32

[Zeng Tao]

For ohci, the maximam supported endpoint number is 32(in and out), and
now we have used (usb_pipeendpoint(pipe) << 1) to index the specified
endpoint descritor, usb_pipeendpoint(pipe) can reach 0xf, so we need
change the NUM_EDs from 8 to 32.
