gpio: qcom_pmic: drop gpio-count property

Browse Source 
This property is not part of the dt bindings and all boards use the new
gpio-ranges property instead. Drop support for this.

Driver for part of pm8916 PMIC - gpio and power/reset keys
This device should be child of SPMI pmic.
1) GPIO driver
Required properties:
- compatible: "qcom,pm8916-gpio"
- reg: peripheral ID, size of register block
- gpio-controller
- gpio-count: number of GPIOs
- #gpio-cells: 2
Optional properties:
- gpio-bank-name: name of bank (as default "pm8916" is used)
Example:
pmic_gpios: gpios@c000 {
compatible = "qcom,pm8916-gpio";
reg = <0xc000 0x400>;
gpio-controller;
gpio-count = <4>;
#gpio-cells = <2>;
gpio-bank-name="pmic";
};
2) Power/Reset key driver
Required properties:
- compatible: "qcom,pm8916-pwrkey"
- reg: peripheral ID, size of register block
- gpio-controller
- #gpio-cells: 2
Optional properties:
- gpio-bank-name: name of bank (as default "pm8916_key" is used)
Example:
pmic_pon: pon@800 {
compatible = "qcom,pm8916-pwrkey";
reg = <0x800 0x96>;
#gpio-cells = <2>;
gpio-controller;
};
