ethernet: Remove casts to same type

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

A function in atl1e_main.c was passed a const pointer
when it actually modified elements of the structure.

Change the argument to a non-const pointer.

A function in stmmac needed a __force to avoid a sparse
warning.  Added it.
