[PATCH v3 2/2] vfio: platform: Add generic DT reset support

Vfio-platform requires reset support, provided either by ACPI, or, on DT platforms, by a device-specific reset driver matching against the device's compatible value. On many SoCs, devices are connected to an SoC-internal reset controller. If the reset hierarchy is described in DT using "resets"
