Platform/RaspberryPi/AcpiTables: Add further named components
Add some additional IORT nodes for the USB & EMMC devices, realistically
we probably only need to have a single node with the lowest AddressSizeLimit
but this is conceptually "cleaner" should anyone actually try and use these
values rather than the _DMA provided ones.
