[kernel] Change grub cmdline to set c-states to 0 for "Intel" CPUs (#6051)
Usually for a use case like networking - should not be configured to reach c6, the maximum used is c1e – due to the added latency getting in & out of states (bad for networking).

Following a recommendation by Intel, networking system should avoid getting in & out of states which introduce latency. The recommended state is c1e and no state change enabling.

In addition, c-state sole purpose is to save power and when inside a networking switch its really negligent being such a tiny consumer vs. the whole cluster.
