f3eed1c7d7 MMU: correctly map MMIO/PCIe ranges 
Previously all MMIO was mapped twice with different attributes
which may or may not lead to strange behaviour when the same
physical range is accessed from both mappings.

We now have a better idea which ranges require nGnRE and nGnRnE
and can just do it correctly instead.

1ccf2e2af5 utils.h: add writeread{8,16,32,64} 
These functions all perform a store direcly followed by a load.
This is useful to e.g. useful to find busy bits which might
already be cleared a few cycles after a write.

24938db17a MMU: use alle2 instead of vmalls12e1is to invalidate TLBs 
I can't remember why I used vmalls12e1is but this leads to
the following bug:

  1. Load m1n1 with normal MMU setup
  2. Disable all mappings, recompile and chainload to that m1n1
  3. Everything will work fine for a while even though it should explode
     when enabling the MMU.

This happens becuse there are still stale TLB entries in some cache.
