* Qualcomm Atheros mobile chipsets

Required properties:
    - compatible: Can be "qca,ar6004-sdio" for SDIO device and
    "qca,ar6004-hsic" for HSIC devcie.
    - qca,chip-pwd-l-gpios: specify GPIO for CHIP_PWD_L.

Optional Properties:
    - cell-index: WLAN Hardware index.
    - qca,pm-enable-gpios: Specify this GPIO if internal PMU needs to be used.
    - qca,ar6004-vbatt-supply: Specify this if VBATT is provided through a
    regulator.
    - qca,ar6004-vdd-io-supply: Specify this if VDD-IO is provided through a
    regulator.

Example:

	wlan0: qca,wlan {
		cell-index = <0>;
		compatible = "qca,ar6004-sdio";
		qca,chip-pwd-l-gpios = <&msmgpio 62 0>;
		qca,pm-enable-gpios = <&pm8019_gpios 3 0x0>;
		qca,ar6004-vdd-io-supply = <&pm8019_l11>;
	};

Update device tree document for AR6003
dt: Update device tree document for AR6003

Update device tree document with properties required for AR6003
SDIO device.
Also change regulator properties to not to prefix chip name as
regulator preperty only reflects regulator to be used.
