power: reset: remove unused imx-snvs-poweroff driver
There's no user of it in kernel now and it basically functions the same as the generic syscon-poweroff.c to which we have already switched. So let's remove it.

-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@20cc000 {
- 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>;
- };
- }
