- Add aardvark support for DEVCAP2, DEVCTL2, LNKCAP2 and LNKCTL2 registers
  (Pali Rohár)

- Clear all MSIs at setup to avoid spurious interrupts (Pali Rohár)

- Disable bus mastering when unbinding host controller driver (Pali Rohár)

- Mask all interrupts when unbinding host controller driver (Pali Rohár)

- Fix memory leak in host controller unbind (Pali Rohár)
