ASoC: doc: cs35l56: Update firmware filename description for B0 silicon 



Update the text for firmware file naming to show that the l?u? suffix is
supported on CS35L56 B0 silicon and ampN was only used on early firmware.

The previous version of this text only said that B0 silicon used the ampN
suffix. Since kernel 6.16 the driver supports both the old ampN and
new l?u? suffix for B0 silicon. New firmwares will use the l?u? suffix.

The CS35L56 Rev B0 continues to use the old filename scheme because a

large number of firmware files have already been published with these

names.

Early firmware for CS35L56 Rev B0 used the ALSA prefix (ampN) as the

filename qualifier. Support for the l?u? qualifier was added in kernel 6.16.
