From: Tirumala Marri <tmarri@apm.com>

Add Synopsys DesignWare HS USB OTG driver kernel configuration.
Synopsys OTG driver may operate in  host only, device only, or OTG mode.
The driver also allows user configure the core to use its internal DMA
or Slave (PIO) mode.

    Haven't we recently agreed with Greg on drivers/usb/dwc/?
