Update the ACPI device information for ARM Juno.

These patches correct a number of problems with the JUNO ACPI tables.

First, put CCA attributes on the devices which can do DMA. This is
because the linux kernel now requires ARM64 devices specify a coherency
model. Without CCA the devices are unable to perform DMA.

Update the EHCI window to a full 64k as documented in the
Juno Platform SoC TRM. This makes it match the values used in some
other places.

Finally, add some _DSD entries for the SMSC ethernet chip.
The latter changes are required for the mainline kernels to use the adapter.
