Subject: [PATCH 01/10] mm: make cleancache.c explicitly non-modular

The Kconfig currently controlling compilation of this code is:

config CLEANCACHE
        bool "Enable cleancache driver to cache clean pages if tmem is present"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
