aarch64 haskell: use ppn concept for PageTablePTEs 
Don't store the bottom 12 bits of the base address for page table PTEs,
because we know they are zero. This gives us implicit alignment to
pageBits in the page table walker.

The C code stores only 36 significant bits, whereas this commit still
uses a full 64-bit machine word for the ppn in Haskell. To be adjusted
in a future change.
