Patrick Georgi c75c79bd02 mptable: Get rid of fixup_virtual_wire
As stated in some code files, fixup_virtual_wire was established
to avoid touching 200 invocations of the mptable code.

Let Coccinelle do it:
  @@
  type T;
  identifier v;
  @@
  -void fixup_virtual_wire(T v)
  -{ ... }

  @@
  expression A;
  identifier v;
  @@
  -v = smp_write_floating_table(A);
  +v = smp_write_floating_table(A, 0);

  @@
  expression A;
  identifier v;

  -v = smp_write_floating_table(A, 0);
  -fixup_virtual_wire(v);
  +v = smp_write_floating_table(A, 1);
