- Add a new compatible string for the Armada 3700 SoCs - add sbuscfg support for orion usb controller driver. For the SoCs without hlock, need to program BAWR/BARD/AHBBRST fields in the sbuscfg register to guarantee the AHB master's burst would not overrun or underrun the FIFO. - the sbuscfg register has to be set after the usb controller reset, otherwise the value would be overridden to 0. In order to do this, the reset callback is registered.
