    config: Remove acpi_idle and intel_idle command lines options
    
    These options were set historically to limits C-states but over time,
    these have become less useful and potentially hazardous.
    
    1. The C1 state may not exist due to BIOS settings. For example, C1
       may not be enabled, but C1E does resulting in excessive polling
       and a failure to ever idle.
    
    2. There may be no idle driver at all if its disabled in the BIOS
    
    3. The idle driver for the machine could be CPPC-based in which case
       the option is simply ignored.
    
    The decision to limit c-states should be an explicit decision for
    a deployment and limited either via the command line or more reliably
    via /dev/cpu_dma_latency.
