DWC OTG host mode improvements. Add support for the 3-strikes and you are
gone rule. Optimise use of channels so that when a channel
is not ready another channel is used. Instead of using the SOF interrupt
use the system timer to drive the host statemachine. This might
give lower throughput and higher latency, but reduces the CPU usage
significantly. The DWC OTG host mode support should not be considered
for serious USB host controller applications. Some problems are still
seen with LOW speed USB devices.
