Subject: [RFC PATCH 01/13] powerpc/book3s: Add missing <linux/sched.h> include

The functions here use struct thread_struct fields, so need to import
the full definition from <linux/sched.h>. The <asm/current.h> header
that defines current only forward declares struct thread_struct.

Failing to include this <linux/sched.h> header leads to a compilation
error when a translation unit does not also include <linux/sched.h>
indirectly.
