cpufreq: integrator: Use set_cpus_allowed_ptr

Several years ago there was an effort to convert all uses of
set_cpus_allowed to use set_cpus_allowed_ptr with the goal of eventually
removing the current definition of set_cpus_allowed and renaming
set_cpus_allowed_ptr as set_cpus_allowed
(https://lkml.org/lkml/2010/3/26/59). This is another step in this
direction.

The Coccinelle semantic patch that makes this change is as follows:

// <smpl>
@@
expression E1,E2;
@@

- set_cpus_allowed(E1, cpumask_of_cpu(E2))
+ set_cpus_allowed_ptr(E1, cpumask_of(E2))

@@
expression E;
identifier I;
@@

- set_cpus_allowed(E, I)
+ set_cpus_allowed_ptr(E, &I)
// </smpl>
