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.
