In powerpc, CONFIG_KVM is bool, and so are these three subarch
options, for the 44x and e500 variants. This means that any
module_exit() calls and functions used by them such as the
kvmppc_booke_exit() are dead code. Here we remove them.
In addition, rather than use module_init, which is just
__initcall for non-modules, we update those as well.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of subsys_initcall (which
seems to make sense for netfilter code) will thus change this
registration from level 6-device to level 4-subsys (i.e. slightly
earlier).
However no impact of that small difference is expected,
since the arch independent kvm code doesn't trigger any init;
it is the arch initcalls here which actually call kvm_init.
