ub: uburma add cmd create jfce implementation. 



driver inclusion
category: feature
bugzilla: NA
CVE: NA

--------------------------------

Uburma add implementations of handling create jfce cmd from
user layer.

This will make kernel possible to handle urma_create_jfce
api in user-layer urma.

Create jfce will finally call ubcore_create_jfce. The created jfce
will be related to a uobj.
