        src/sys/dev/acpi: acpi_cpu_cstate.c

Log Message:
Disable read of the ACPI timer during idle, fixing performance degradation
observed with acpicpu.  C1 (MWAIT) is the deepest sleep currently enabled so
there should be no functional change.  Also, the computed nap time is run
through hztoms() which seems incorrect as the ACPI timer is running in the
MHz range.
