ls2080: Exit dpaa only right before exiting U-Boot
On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.
Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.
So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.
For existing boot scripts, nothing should change with this patch.

operations; invalidate and flush of both dcache and icache (note that
only 3 of the 4 possible combinations make sense, since the icache never
contains dirty lines). This patch adds an optional hook for all
implemented cache-wide operations, and renames the one existing hook to
better represent exactly which operation it is implementing. A dummy
no-op implementation of each hook is provided.
