usb: musb: NAK timeout scheme on bulk TX endpoint
Fixes endpoint starvation issue when more than one bulk QH is
multiplexed on the reserved bulk TX endpoint.
This patch sets the NAK timeout interval for such QHs, and when
a timeout triggers the next QH will be scheduled.
This scheme doesn't work for devices which are connected to a
high to full speed tree (transaction translator) as there is
no NAK timeout interrupt from the musb controller from such
devices.
