ASoC: atmel: atmel_ssc_dai: Drop S24_LE support due to single channel limitation 

Drop S24_LE format because it is not supported if more than 2 channels
(of TDM slots) are used. This limitation makes it impractical for use cases
requiring more than 2 TDM slots, leading to potential issues in
multi-channel configurations.
