powerpc/mm/radix: mark as __tlbie_pid() and friends as__always_inline

Browse Source 
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place.  We need to eliminate potential issues beforehand.

If it is enabled for powerpc, the following errors are reported:

  arch/powerpc/mm/tlb-radix.c: In function '__tlbie_lpid':
  arch/powerpc/mm/tlb-radix.c:148:2: warning: asm operand 3 probably doesn't match constraints
    asm volatile(PPC_TLBIE_5(%0, %4, %3, %2, %1)
