Subject: [Filter/NNFW] change nnfw api
X-Git-Tag: accepted/tizen/unified/20200723.161155~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=340ac3333a0c910b69e652ff5be62d0fed52ad6f;p=platform%2Fupstream%2Fnnstreamer.git

[Filter/NNFW] change nnfw api

1. Change nnfw api to set input info.
The function apply_tensorinfo will be deprecated soon.
2. Remove unnecessary definition about max rank of nnfw.
