[PATCH 2/2] dt-bindings: mfd: twl4030-audio: document preferred name for external mute

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Proper names for GPIOs should use "-gpios" suffix. Now that the
twl4030 codec driver has been converted to use GPIO descriptors in
commit 178c169a30b0 ("ASoC: codec: twl4030: Convert to GPIO
descriptors"), update the binding documentation to list
"ti,hs_extmute-gpios" as the preferred property name and mark
"ti,hs_extmute_gpio" as deprecated.
