dt-bindings: pinctrl: qcom,milos-lpass-lpi-pinctrl: Add Eliza pinctrl

Document compatible for Qualcomm Eliza SoC LPASS LPI pin controller.
Eliza has the same pin mux functions as Milos but uses a different
slew rate register layout where the slew rate field is in the same
GPIO config register rather than a separate dedicated register. As a
result, Eliza only has a single reg entry instead of two.
