Hi all,

In this series, I add several new interfaces for chipidea driver,
they are mainly for system configuration adjustment. The USB
performance may be improved with these configuration changing,
but each vendor driver owner needs to consult with your IC
owner which configuration parameters are suitable for your system
before changing it, and only change it if necessary.

The other changes are for imx, it shows how imx uses these interfaces.
Shawn, the patch [5/10] and [9/10] are dts changes, help to review it
please.

Changes for v2:
- Use the bit fields which are not used. [Patch 2/10, 6/10, 10/10]
- According to Greg and Sascha comments, format patch 2/10's
  commit log.
- using non-burst instead of unburst for patch 7/10
