usb: musb: Ensure that we set musb dynamic FIFO buffer for every endpoint

If we do not set FIFO buffer address and size for some endpoint which is in
use then default programmed address 0x0 would be used which is in conflict
with address of FIFO buffer for endpoint 0. Moreover address of FIFO buffer
for endpoint 0 cannot be programmed, it is fixed to 0x0. Sharing address
space between more endpoints cause data loss and unexpected errors.

This patch is fixing transmission of characters over usbtty serial console
and allows using of usbtty for debugging purposes on Nokia N900.
