powerpc: Fix for getting CPU number in power_save_ppc32_restore()
The calculation to get TI_CPU based off of SPRG3 was just plain wrong,
meaning that we were getting garbage for the CPU number on 6xx/G3/G4
based SMP boxes in this code.
Just offset off the stack pointer (to get to thread_info) like all the
other references to TI_CPU do.
This was pointed out by Chen Gong <G.Chen@freescale.com>
