Add the IFD regions as child devices and set the region access on the child devices. Also add read-only SPI descriptor as an HSI attribute and require FLOCKDN on Intel hardware. Use the hidden PCI 00:1f.5 device to set the SPIBAR automatically and generate the quirk file automatically to support more hardware.
