hwmon: (acpi_power_meter) fix lockdep spew due to non-static lock class
Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a
bug report from someone hitting the same issue in acpi_power_meter.
[ 13.963168] power_meter ACPI000D:00: Found ACPI power meter.
[ 13.963900] BUG: key ffff8802161f3920 not in .data!
[ 13.963904] ------------[ cut here ]------------
[ 13.963915] WARNING: at kernel/lockdep.c:2986
lockdep_init_map+0x52f/0x560()
So let's fix that up for them by statically declaring the
lockdep_class_key.
