ARM: dts: imx6ul-pico: Use #pwm-cells = <3> for imx27-pwm device

Browse Source 
The binding dictates using 3 pwm-cells. Adhere to that.

This fixes the following dtbs_check warnings:

	arch/arm/boot/dts/nxp/imx/imx6ul-pico-dwarf.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#
