xhci doesn't work with macos because macos has a white list of supported xhci controllers and ignores the xhci adapters emulated by qemu.

Running `system_profiler SPUSBDataType` on macOS guest confirms that the system "sees" my device, and that qemu is passing *something* through. However, the system sees my connection as USB 2.0, even though i'm passing through XHCI controllers (nec-usb-xhci/qemu-xhci). I suspect this is the reason why my guest is unable to recognize my iPhone in XCode & iTunes. Parameters: QEMU release version: 2.10.0-rc0 Bios: [patched version of OVMF](https://github.com/gsomlo/edk2/tree/macboot)] Command Line: https://pastebin.com/pBSYbrW1 Host: Arch Linux Guest: macOS v10.12.6 Guest System Info: https://pastebin.com/U1Tihxei Notes: 1. Observed sometime after late-May-early-June of this year. 2. Due to [a defect in qemu v2.8 which affected GTK users](https://bugs.launchpad.net/qemu/+bug/1578192), and [a recent change to macOS' booting process conflicting with qemu v2.9](https://lists.nongnu.org/archive/html/qemu- devel/2017-03/msg06366.html), i'm forced to use qemu v2.10.0-rc0 (as -rc1 fails to load OVMF right now).
