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.

another one ? Greg, I know MUSB is also wrong, but can we avoid adding
more guys to drivers/Makefile and use drivers/usb/Makefile instead ?
Promise I'll send a patch to MUSB for next merge window :-)

It appears this depends on host support? I get compile errors when I
have this selected and no host support enabled.
