xen/tmem: Split out the different module/boot options.
There are three options - depending on what combination of CONFIG_FRONTSWAP, CONFIG_CLEANCACHE and CONFIG_XEN_SELFBALLOONING is used. Lets split them out nicely out in three groups to make it easier to clean up. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
