The usbip stack handles the kmalloc and kfree of the transfered buffers. Some
USB-Stacks add the flag URB_FREE_BUFFER to their urbs, so the usb layer removes
it in usb_free_urb. This can lead to double free situations as the usbip stack
already removes its created buffers. To avoid that we remove t

We have one register for each EP to set the maximum packet size for both
TX and RX.
If for example an RX programming would happen before the previous TX
transfer finishes we would reset the TX packet side.
To fix this issue, only modify the TX or RX part of the register.

For the DMA we have ch (channel), dmareq and sync_dev parameters both
within the tusb_omap_dma_ch and tusb_omap_dma_ch struct.
By creating a common struct the code can be simplified when selecting
between the shared or multichannel DMA parameters.

Instead of requesting the DMA channel in tusb_omap_dma_allocate() do it
when the controller is created and in runtime work from the DMA channel
pool.
This change is needed for the DMAengine conversion of the driver since the

Having one musb_ep_select() instead the two calls in if/else is the same
thing, but makes the code a bit simpler to follow.

When using the g_ncm for networking this flag will make sure that the
buffer is alligned to 32bit so the DMA can be used to offload the data

XHCI specification 1.1 does not require xHCI 1.0 compliant controllers
to always enable hardware USB2 LPM.
However, the current xHCI driver always enable it by setting HLE=1 when
seeing HLC=1. This makes certain xHCI controllers that have broken USB2
HW LPM fail to work as there is no way to disabl
