[PATCH 0/2] Add Versal PUF support

[Harsh Jain]

Versal devices contain a physically unclonable function (PUF) block
that derives device-unique secrets from intrinsic silicon characteristics.

Add a misc character driver to support PUF registration and regeneration.
Registration generates a unique secret and outputs binary helper data
that can later be used during regeneration to reproduce the same
secrets.
