arm: Replicate the PageBytes constant in the ArmSystem class.

When isa_traits.hh hopefully goes away in the not too distant future,
this constant will need somewhere to live so ARM components can find it.
There are valid arguments that this should not be a constant in the
first place, but that's outside the scope of this change.
