At some point PWM cell count was changed, but it didn't triggered any
It changed in this commit:

ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files
The imx-pwm driver supports 3 cells and this is the more flexible setting. So use it by default and overwrite it back to two for the files that reference the PWMs with just 2 cells to minimize changes.
This allows to drop explicit setting to 3 cells for the boards that already depend on this. The boards that are now using 2 cells explicitly can be converted to 3 individually.
