[PATCH v6 3/4] dt-bindings: pwm: add IPQ6018 binding

[Baruch Siach <baruch@tkos.co.il>]

DT binding for the PWM block in Qualcomm IPQ6018 SoC.

Signed-off-by: Baruch Siach <baruch@tkos.co.il>

v6:

  Device node is child of TCSR; remove phandle (Rob Herring)

  Add assigned-clocks/assigned-clock-rates (Uwe Kleine-König)

v5: Use qcom,pwm-regs for phandle instead of direct regs (Bjorn
    Andersson, Kathiravan T)

v4: Update the binding example node as well (Rob Herring's bot)

v3: s/qcom,pwm-ipq6018/qcom,ipq6018-pwm/ (Rob Herring)

v2: Make #pwm-cells const (Rob Herring)
