Production silicon for CS36L63 has some small differences compared to
pre-production silicon. Update firmware addresses, which are different.
No product was ever released with pre-production silicon so there is no
need for the driver to include support for it.
Fixes: d3197a09a117 ("ASoC: cs35l56: Add initial support for CS35L63 for I2C and SoundWire")

CS35L63 uses different algorithm IDs from CS35L56.
Add a new mechanism to handle different alg IDs between parts in the
CS35L56 driver.

Production silicon for CS36L63 has some small differences compared to
pre-production silicon. Remove soundwire clock workaround as no
longer necessary. We don't want to do tricks with low-level clocking
controls if we don't need to.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
