This change adds support for accessing the USB shim from within the kernel. Note that this change by itself does not allow the kernel to act as a host or as a device; it merely exposes the built-in on-chip hardware to the kernel. The <arch/usb_host.h> and <arch/usb_host_def.h> headers are empty at the moment because the kernel does not require any types or definitions specific to the tilegx USB shim; the generic USB core code is all we need. The headers are left in as stubs so that we don't need to modify the hypervisor header (drv_usb_host_intf.h) from upstream. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
