[PATCH 06/14] leon3: replace PROP_PTR with PROP_LINK

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

"set_pil_in" and "set_pil_in" are used to set a callback, but have a
single user and cannot be modified by the user.

Simplify the code by calling directly into leon3_set_pil_in(), and use
a "cpu" link property.
