Christopher Obbard 38930ec767 arm64: dts: rockchip: Fix i2s0 pin conflict on ROCK Pi 4 boards 
commit 8cd79b729e746cb167f1563d015a93fc0a079899 upstream.

Commit 91419ae042 ("arm64: dts: rockchip: use BCLK to GPIO switch on
rk3399") modified i2s0 to switch the corresponding pins off when idle.
For the ROCK Pi 4 boards, this means that i2s0 has the following pinctrl
setting:

    pinctrl-names = "bclk_on", "bclk_off";
    pinctrl-0 = <&i2s0_2ch_bus>;
    pinctrl-1 = <&i2s0_8ch_bus_bclk_off>;

Due to this change, i2s0 fails to probe on my Radxa ROCK 4SE and ROCK Pi
4B boards:

    rockchip-pinctrl pinctrl: pin gpio3-29 already requested by leds; cannot claim for ff880000.i2s
    rockchip-pinctrl pinctrl: pin-125 (ff880000.i2s) status -22
    rockchip-pinctrl pinctrl: could not request pin 125 (gpio3-29) from group i2s0-8ch-bus-bclk-off  on device rockchip-pinctrl
    rockchip-i2s ff880000.i2s: Error applying setting, reverse things back
    rockchip-i2s ff880000.i2s: bclk disable failed -22

A pin requested for i2s0_8ch_bus_bclk_off has already been requested by
user_led2, so whichever driver probes first will have the pin allocated.

The hardware uses 2-channel i2s so fix this error by setting pinctl-1 to
i2s0_2ch_bus_bclk_off which doesn't contain the pin allocated to user_led2.

I checked the schematics for all Radxa boards based on ROCK Pi 4 and this
change is compatible with all boards.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
