Using the RT5616 codec to replace the CS46l63 in the V2.9.0 SDK

Hi Nordic team.

We are developing the LE audio product, and have questions here.

We have design a headset board using the RT5616 as codec.

The modifications here are as follows on the V2.9.0.

1, Disable the board check by disable code.

2, using the internal 32.768Khz by CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y in the prj.conf

3, Disable the CS43l63 code.

4, Addingt the RT5616 code at the I2C.

5, change the GPIOs of the LED/KEY/UART

6, Setting the BLE CIS mode

Testing relult:

1,Project is running normal, the log is okay by UART

2, LED is okay

3, RT5616 inital is okay

4, BLE can be connected with the USB dongle( it's the nRF5340 Audio DK board with PCA1021, and then writed the usb dongle 's FW of the CIS )

Issues:

1,There are the issues log bellow when the BLE is connect. Could you tell me where is this issue come frome?

2,There are have more issues log bellow when the audio stream is working,Could you tell me where is this issue come frome?

3, Base on the above issues,

Could you tell me how to remove the CS43l63 step by step in the device tree file and prj.conf file and coding?(I am a newbie and not familiar with SDK,I am only disable the all code about CS43l63)

Thank you very munch!
