ASoC: cs35l56: Add support for CS35L54 and CS35L57
The CS35L54 and CS35L57 are Boosted Smart Amplifiers. The CS35L54 has I2C/SPI control and I2S/TDM audio. The CS35L57 also has SoundWire control and audio. The hardware differences between L54, L56 and L57 do not affect the driver control interface so they can all be handled by the same driver.
