dm: enable lpss device passthrough
58a9c3d 
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.
