MFC r285914, r289029 and r289560:
- Move the remainder of host controller capability registers reading from
xhci_start_controller() to xhci_init(). These values don't change at run-
time so there's no point of acquiring them on every USB_HW_POWER_RESUME
instead of only once during initialization. In r276717, reading the first
couple of registers in question already had been moved as a prerequisite
for the changes in that revision.
- Identify ASMedia ASM1042A controllers.
- Use NULL instead of 0 for pointers.
- Add quirks for USB 3.0 PCI devices.

Various XHCI fixes and improvements:
- Improve and fix MSI interrupt allocation, setup and release.
- Add missed flushing of data which can happen when "xhci_configure_mask()"

error feature is always enabled except for ISOCHRONOUS transfers.
- Allow systems having a page size greater than 4K to use fewer
scatter-gather XHCI TRB entries for its payload data. The XHCI

entry.

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel

Commit initial version of new XHCI driver which was written from
scratch. This driver adds support for USB3.0 devices. The XHCI
interface is also backwards compatible to USB2.0 and USB1.0 and will
evntually replace the OHCI/UHCI and EHCI drivers.

There will be follow-up commits during the coming week to link the
driver into the default kernel build and add missing USB3.0
functionality in the USB core. Currently only the driver files are
committed.
