Subject: [PATCH 4.16 082/279] ARM: dts: da850: fix W=1 warnings with pinmux node

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sekhar Nori <nsekhar@...com>

[ Upstream commit 94a82284ad4711b7f9fd78981fdc7a1cb645030b ]

Remove unused #address-cells and #size-cells from pinmux
node. This fixes W=1 warnings of the type:

arch/arm/boot/dts/da850-lcdk.dtb: Warning (avoid_unnecessary_addr_size): /soc@...0000/pinmux@...20: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

Tested on DA850 LCDK by checking output of:

/sys/kernel/debug/pinctrl/1c14120.pinmux-pinctrl-single/pins

before and after the change.
