[POC 02/12] init/main.c: call update_rai_access()

[Rasmus Villemoes]

I hope that one can actually interchange the order of these calls a bit
so that they read

	mark_readonly();
	update_rai_access();
	free_initmem();

because there will be some metadata associated to each rai_* macro
invocation that might as well live in __initdata. But for now, we will
live with that wasted space.
