a40840f13c proxy: Expose usb_iodev_vuart_setup 
Expose the usb_iodev_vuart_setup function in uartproxy. This opens
the secondary ACM pipe to new uses outside the hypervisor. E.g. it can
be set up as another stream for sending proxy requests.

Sample usage from proxyclient:

    p.usb_iodev_vuart_setup(p.iodev_whoami())
    p.iodev_set_usage(IODEV.USB_VUART, USAGE.UARTPROXY)
    # the second virtual serial now also serves proxy

de6979fc7b Revert "usb: Add usb_idx_from_address() to find a dev by its MMIO addr" 
This is no longer needed, so put things back the way they were.

This reverts commit e689ceb263.

555965e98a pcie: Calculate the number of reg entries per port 
Turns out this isn't hardware-specific, but rather a change Apple made
retroactively in 12.0 RC. Doesn't look like there's a saner way than
this...
