The driver "drivers/pwm/pwm-imx27.c" never use interrupt. Generally pwm
hardware generate a waveform according to register timing setting. Needn't
interrupt handle at all. So remove it from "required" list.

Use #pwm-cells for all i.MX variants. Only fsl,imx1-pwm does not support
inverted PWM output. Keep it the same for consistency.

Document all ARMv5, ARMv6 and ARMv7 i.MX compatibles to fix dtbs_check
warnings like:

DTSes with new i.MX 8M SoCs introduce their own compatibles so add them
to fix dtbs_check warnings like:

compatible:0: 'fsl,imx8mm-pwm' is not one of ['fsl,imx1-pwm', 'fsl,imx27-pwm']
From schema: Documentation/devicetree/bindings/pwm/imx-pwm.yaml
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: pwm@30660000:
compatible: ['fsl,imx8mm-pwm', 'fsl,imx27-pwm'] is too long
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: pwm@30660000:
compatible: Additional items are not allowed ('fsl,imx27-pwm' was unexpected)

There's no need to specify 'maxItems' with the same value as the number
of entries in 'items'. A meta-schema update will catch future cases.
