[PATCH v2 06/13] kho: Always expose output FDT in debugfs

[Pasha Tatashin]

Currently, the output FDT is added to debugfs only when KHO is
finalized and removed when aborted.

There is no need to hide the FDT based on the state. Always expose it
starting from initialization. This aids the transition toward removing
the explicit abort functionality and converting KHO to be fully
stateless.
