usb: m66592-udc buffer management update
This patch updates the m66592-udc buffer management code.
Use fixed buffers for bulk and isochronous pipes, also make
sure to handle the isochronous-as-bulk case. With fixed buffers
there is no need to keep track of used buffers with bi_bufnum.
Also, this fixes a potential buffer offset problem where the
base offset incorrectly varies with the number of pipes used.
With this patch applied it is possible to use m66592-udc for
both Ethernet and Serial using CONFIG_USB_CDC_COMPOSITE.
