powerpc/e500mc: Remove dead L2 flushing code in idle_e500.S

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

This code can never be executed as it is only built when
CONFIG_PPC_E500MC is unset, but the only CPUs that have CPU_FTR_L2CSR
require CONFIG_PPC_E500MC and do not have the MSR/HID0-based nap
mechanism that this file uses.
