src/sys/dev/acpi: acpi_cpu.c acpi_cpu.h acpi_cpu_cstate.c
XXX: If this is not correct, revert or fix.
This makes my laptop boot instead of panic:
panic: kernel diagnostic assertion "native_idle != NULL" failed: file
"../../../../arch/x86/acpi/acpi_cpu_md.c", line 155
fatal breakpoint trap in supervisor mode

1. ACPI seems to define cpuids 1..n; we define 0..n-1. Adjust for that
2. My laptop is dual core, but ACPI reports 4 cpu nodes. Instead of
attaching the unmatched ones, make the match fail. Do we want to
attach and do nothing instead?
3. Create a flag, and only set it after we are completely initialized,
so the sysmon thread does not try to access unitialized state.
