staging: wilc1000: wilc_wfi_cfgoperations: remove cast on void pointers

Remove cast on void pointers. C programming language guarantees
the conversion from void pointer to any other pointer type.

Coccinelle patch:
@r@
expression x;
void* e;
type T;
identifier f;
@@

(
  *((T *)e)
|
  ((T *)x)[...]
|
  ((T *)x)->f

- (T *)
