power: reset: imx-snvs-poweroff: add power off driver for i.mx6
This driver register pm_power_off with snvs power off function. If your boards NOT use PMIC_ON_REQ to turn on/off external pmic, or use other pin to do, please disable the driver in dts, otherwise, your pm_power_off maybe overwrote by this driver.

+i.mx6 Poweroff Driver
+
+SNVS_LPCR in SNVS module can power off the whole system by pull
+PMIC_ON_REQ low if PMIC_ON_REQ is connected with external PMIC.
+If you don't want to use PMIC_ON_REQ as power on/off control,
+please set status='disabled' to disable this driver.
+
+Required Properties:
+-compatible: "fsl,sec-v4.0-poweroff"
+-reg: Specifies the physical address of the SNVS_LPCR register
+
+Example:
+ snvs@020cc000 {
+ compatible = "fsl,sec-v4.0-mon", "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x020cc000 0x4000>;
+ .....
+ snvs_poweroff: snvs-poweroff@38 {
+ compatible = "fsl,sec-v4.0-poweroff";
+ reg = <0x38 0x4>;
+ };
+ }
