kernel - Change cpu_idle_hlt default
* Set cpu_idle_hlt default to 1 for Intel Haswell or later cpus. These
cpus do major power management in the HLT instruction.
Leave cpu_idle_hlt default at 2 for AMD cpus or older Intel cpus.
These cpus do not do major management in the HLT instruction and ACPI
entry is required to reduce idle power consumption.
