schemas: legacy: NVME1000: Add EnablePEC property

This commit adds `EnablePEC` property to the schema of `NVME1000`
sensor. This, if set to true, will enable SMBus PEC generation and
verification in the device driver. nvmesensor daemon in dbus-sensors
repository will consume this property in the related change [1].
