The binding dictates using 3 pwm-cells. Adhere to that. This fixes the following dtbs_check warnings: arch/arm/boot/dts/nxp/imx/imx6sx-sdb-reva.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6sx-sdb-sai.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6sx-sdb.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# arch/arm/boot/dts/nxp/imx/imx6sx-sdb-mqs.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml# There is no need for an explicit status = "okay" in the pwm node as the soc dtsi doesn't disable this device. Drop this property, too.
