This brings in the "-w" option from bhyve to ignore unknown MSRs.
It will make debugging Linux guests a bit easier.

USB method structures for USB controllers and USB pipes should be
constant and does not need to be modified. This also saves a small
amount of RAM.

Merge fresh head.

Revert r251023 until a more proper solution is found
for ATI based USB controllers.

Workaround for for a problem seen with ATI Technologies EHCI
controller hardware most likely present on UHCI chipsets aswell. The
bug manifests itself when issuing isochronous transfers and bulk
transfers towards the same device simultaneously. From time to time it
happens that either the completion IRQ was missing or that the
completion IRQ was happening before the ITD/SITD was completely
written back to memory. The workaround assumes that double buffered
isochronous transfers are used, and that a second interrupt is
generated at the beginning of the next isochronous transfer to
complete the previous one. Possibly skipping the interrupt at the last
isochronous frame is possible, but will then break single buffered
isochronous transfers. For now we can live with some extra interrupts.

Modify the FreeBSD USB kernel code so that it can be compiled directly
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
- console in loader via USB
- loading kernel via USB

Discussed with: Hiroki Sato, hrs @ EuroBSDCon

Make several timing parameters of the USB enumeration sequence tuneable.
Also update the port reset time from 250ms to 50ms. Some USB devices
have a hard limit in hardware at 222ms for the port reset time and will
not enumerate unless this delay is closer to the usb.org defined value.
This patch can fix enumeration with some USB devices.

Inherit USB mode from RootHUB port where the USB device is connected.
Only RootHUB ports can be dual mode. Disallow OTG ports on external HUBs.
This simplifies some checks in the USB controller drive
