powerpc: Use set_cpus_allowed_ptr

Use set_cpus_allowed_ptr rather than set_cpus_allowed.

The semantic patch that makes this change is as follows:

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)
