Subject: [PATCH v16 9/9] arm64: dts: qcom: ipq9574: add pwm node

From: George Moussalem <george.moussalem@...look.com>

Describe the PWM block on IPQ9574.

Although PWM is in the TCSR area, make pwm its own node as simple-mfd
has been removed from the bindings and as such hardware components
should have its own node.
