srcu: Move SRCU Tree/Tiny definitions from srcu.h

Browse Source 
There are a couple of definitions under "#ifdef CONFIG_TINY_SRCU"
in include/linux/srcu.h.  There is no point in them being there,
so this commit moves them to include/linux/srcutiny.h and
include/linux/srcutree.c, thus eliminating that #ifdef.
