powerpc/spe: Mark expected switch fall-throughs

Mark switch cases where we are expecting to fall through.

Fixes errors such as below, seen with mpc85xx_defconfig:

  arch/powerpc/kernel/align.c: In function 'emulate_spe':
  arch/powerpc/kernel/align.c:178:8: error: this statement may fall through
    ret |= __get_user_inatomic(temp.v[3], p++);
