[PULL 3/5] target/mips: Remove stale TODO file

[Laurent Vivier]

From: Thomas Huth <thuth@redhat.com>

The last change to this file has been done in 2012, so it
seems like this is not really used anymore, and the content
is likely very out of date now.

-  QEMU's softmmu implements a x86-style MMU, with separate entries
-  for read/write/execute, a TLB index which is just a modulo of the
-  virtual address, and a set of TLBs for each user/kernel/supervisor
-  MMU mode.
-  MIPS has a single entry for read/write/execute and only one MMU mode.
-  But it is fully associative with randomized entry indices, and uses
-  up to 256 ASID tags as additional matching criterion (which roughly
-  equates to 256 MMU modes). It also has a global flag which causes
-  entries to match regardless of ASID.
-  To cope with these differences, QEMU currently flushes the TLB at
-  each ASID change. Using the MMU modes to implement ASIDs hinges on
-  implementing the global bit efficiently.

of VuVirtqElement".
