Julia Lawall f4ada24bd6 arch/arm/mach-kirkwood: Avoid using ARRAY_AND_SIZE(e) as a function argument
Replace ARRAY_AND_SIZE(e) in function argument position to avoid hiding the
arity of the called function.

The semantic match that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,f;
@@

f(...,
- ARRAY_AND_SIZE(e)
+ e,ARRAY_SIZE(e)
  ,...)
// </smpl>
