Add support for S24_LE format for all internal and IO AHUB modules, except for ASRC (which is already supported). The data flow happens as mentioned below: - ADMAIF picks 24-bit valid data and converts it to 32-bit before sending to internal AHUB modules. This makes the driver change simpler for internal AHUB modules. - IO modules CIF converts the 32-bit data to 24-bit before sending it to the external world. - To maintain consistency across modules, conversions between 24-bit and 32-bit occur either at ADMAIF or at the IO modules CIF. This feature has been thoroughly tested and verified with all internal AHUB modules on the Jetson AGX Orin Platform, as well as with the external RT5640 codec.
