Subject: [PATCH v17 6/9] arm64: dts: qcom: ipq6018: add pwm node

From: Devi Priya <quic_devipriy@...cinc.com>

Describe the PWM block on IPQ6018.

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.
