[PATCH v3 10/12] arm64: dts: qcom: qrb4210-rb2: enable wsa881x amplifier

[Alexey Klimov <alexey.klimov@linaro.org>]

One WSA881X amplifier is connected on QRB4210 RB2 board
hence only mono speaker is supported. This amplifier is set
to work in analog mode only. Also add required powerdown
pin/gpio.
