gpio: qcom_pmic: drop gpio-count property

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;
