x86: Apply more __ro_after_init and const
Guided by grsecurity's analogous __read_only markings in arch/x86,
this applies several uses of __ro_after_init to structures that are
only updated during __init, and const for some structures that are
never updated. Additionally extends __init markings to some functions
that are only used during __init, and cleans up some missing C99 style
static initializers.
