Summary Disable use of HAVE(36BIT_ADDRESS).

We cannot guarantee that the kernel will always map pages with 36-bit addresses. As such, we cannot use HAVE(36BIT_ADDRESS)). For now, we will simply disable the use of HAVE(36BIT_ADDRESS) instead of removing it completely. We will completely remove the HAVE(36BIT_ADDRESS) code after we have some baking time. Also clean up or fix some uses of EFFECTIVE_ADDRESS_WIDTH that fall out of disabling HAVE(36BIT_ADDRESS).
