powerpc/85xx: Add lbc suspend support for PM
Power supply for LBC registers is off when system go to deep-sleep state. We save the values of registers before suspend and restore to registers after resume. We removed the last two reservation arrays from struct fsl_lbc_regs for allocating less memory and minimizing the memcpy size.
