So make interface more consistent with early_res.
Later we can share some code with early_res.

We have almost the same code for mtrr cleanup and amd_bus checkup, and
this code will also be used in replacing bootmem with early_res,
so try to move them together and reuse it from different parts.
Also rename update_range to subtract_range as that is what the
function is actually doing.
