Passthrough of lpss devices, such as sdio, spi, uart, is not supported for user vm due to irq and acpi info missing. Here provides new pci device passthrough options to pass irq and acpi dsdt info by users. Considering spi dsdt info varies from HW, to add the flexibility of configuration, it is designed to pass dsdt file of spi device by users rather than hard code. Besides, remove the limit of the lpss device passthrough for rtvm. Tracked-On: #8615 Signed-off-by: nacui <na.cui@intel.com> Reviewed-by: Jian Jun Chen <jian.jun.chen@intel.com>
