doc: update porting, vfs documentation to describe mmap_prepare()

Browse source

Now that we have established .mmap_prepare() as the preferred means by
which filesystems establish state upon memory mapping of a file, update the
VFS and porting documentation to reflect this.

As part of this change, additionally update the VFS documentation to
contain the current state of the file_operations struct.
