lkp reported warnings in some configuration due to
update_current_thread_amr() being unused:
arch/powerpc/mm/book3s64/pkeys.c:284:20: error: unused function 'update_current_thread_amr'
static inline void update_current_thread_amr(u64 value)
Which is because it's only use is inside an ifdef. We could move it
inside the ifdef, but it's a single line function and only has one
caller, so just fold it in.
Similarly update_current_thread_iamr() is small and only called once,
so fold it in also.
Fixes: 48a8ab4eeb ("powerpc/book3s64/pkeys: Don't update SPRN_AMR when in kernel mode.")
