Subject: [PATCH 2/3] 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.
