powerpc/e500mc: flush L2 on NAP for e500mc
If we have an L2CSR register (e500mc) we need to flush the L2 before going to nap. We use the HW flush mechanism provided in that register. The code reuses the CPU_FTR_604_PERF_MON bit as it is no longer used by any code in the kernel. Additionally we didn't reuse the exist L2CR feature bit as this is intended for the 7xxx L2CR register and L2CSR is part of the new Freescale "Book-E" registers.
