[PATCH for-10.0 0/7] hw/riscv: riscv-iommu-sys device

[Daniel Henrique Barboza]

Hi,

Now that we have merged the base IOMMU support we can re-introduce
the riscv-iommu-sys platform device that was taken away from the initial
posting.

Aside from adding support for the device in the 'virt' machine we're
also adding MSI support for it, something that we weren't doing before.
The Linux driver is then free to choose either MSI or WSI to use the
device.

Patches based on master.
