dwc-hsotg (dwc2) USB host controller emulation

Browse Source 
Add the dwc-hsotg (dwc2) USB host controller emulation code.
Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c.

Note that to use this with the dwc-otg driver in the Raspbian
kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on
the kernel command line.

Emulation of slave mode and of descriptor-DMA mode has not been
implemented yet. These modes are seldom used.

I have used some on-line sources of information while developing
this emulation, including:

http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf
which has a pretty complete description of the controller starting
on page 370.

https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf
which has a description of the controller registers starting on
page 130.

Thanks to Felippe Mathieu-Daude for providing a cleaner method
of implementing the memory regions for the controller registers.
