Subject: [PATCH v1 1/2] arm64: dts: rockchip: Add i2s0-2ch-bus-bclk-off pins to RK3399

Commit 0efaf8078393 ("arm64: dts: rockchip: add i2s0-2ch-bus pins on
rk3399") introduced a pinctl for i2s0 in two-channel mode. Commit
91419ae0420f ("arm64: dts: rockchip: use BCLK to GPIO switch on rk3399")
modified i2s0 to switch the corresponding pins off when idle.

Although an idle pinctrl node was added for i2s0 in 8-channel mode, a
similar idle pinctrl node for i2s0 in 2-channel mode was not added. Add
it.

Fixes: 91419ae0420f ("arm64: dts: rockchip: use BCLK to GPIO switch on rk3399")
