The Rockchip PX30 SoC has three I2S controllers, i2s1 and i2s2 are
2-channel I2S/PCM controllers handled by the same controller driver, and
i2s0 a 8-channel I2S/PCM/TDM controller handled by another controller
driver.

This adds the device tree node required to enable I2S0 on PX30.

This was tested in a 2-channel I2S with TX BCLK/LRCK for both TX and RX
(rockchip,trcm-sync-tx-only) setup on a soon-to-be-released board.

The Gru-Scarlet family includes a variety of SKU identifiers, using
parts of a 3-bit space {0..7}. SKU2 and SKU4 devices (under a few
different manufacturer names) also use the Innolux display.

Without this, a SKU2 device may non-deterministically (depending on the
matching order of DTBs and bootloader behavior) select either one of the
INX DTBs (rk3399-gru-scarlet-dumo.dtb or rk3399-gru-scarlet-inx.dtb) or
the KingDisplay DTB (rk3399-gru-scarlet-kd.dtb), to ill effect.

We discoverd that the state of BCLK on, LRCLK off and SD_MODE on
may cause the speaker melting issue. Removing LRCLK while BCLK
is present can cause unexpected output behavior including a large
DC output voltage as described in the Max98357a datasheet.

In order to:
  1. prevent BCLK from turning on by other component.
  2. keep BCLK and LRCLK being present at the same time

This patch adjusts the device tree to allow BCLK to switch
to GPIO func before LRCLK output, and switch back during
LRCLK is output.

Anbernic RG353P and RG503 are both RK3566 based handheld gaming devices
from Anbernic.

Both devices have:
 - 2 SDMMC slots.
 - A Realtek rtl8821cs WiFi/Bluetooth adapter.
 - A mini HDMI port.
 - A USB C host port and a USB C otg port (currently only working as
   device).
 - Multiple GPIO buttons and a single ADC button.
 - Dual analog joysticks controlled via a GPIO mux.
 - A headphone jack with amplified stereo speakers via a SGM4865 amp.
 - A PWM based vibrator for force feedback.

The RG353P has:
 - 2GB LPDDR4 RAM.
 - A 32GB eMMC.
 - A 3.5 inch 640x480 4-lane DSI panel of unknown origin with an i2c
   controlled touchscreen (touchscreen is a Hynitron CST340).

The RG503 has:
 - 1GB LPDDR4 RAM.
 - A 5 inch 960x544 AMOLED 2-lane DSI/DBI panel manufactured by Samsung
   with part number ams495qa04. Data for this panel is provided via the
   DSI interface, however commands are sent via a 9-bit 3-wire SPI
   interface. The MISO pin of SPI3 of the SOC is wired to the input of
   the panel, so it must be bitbanged.

This devicetree enables the following hardware:
 - HDMI (plus audio).
 - Analog audio, including speakers.
 - All buttons.
 - All SDMMC/eMMC/SDIO controllers.
 - The ADC joysticks (note a pending patch is required to use them).
 - WiFi/Bluetooth (note out of tree drivers are required).
 - The PWM based vibrator motor.

The following hardware is not enabled:
 - The display panels (drivers are being written and there are issues
   with the upstream DSI and VOP2 subsystems).
 - Battery (driver pending).
 - Touchscreen on the RG353P (note the i2c2 bus is enabled for it).
