Since the host command number 0x012B conflicts with other EC host
command, add one to all regulator control related host command.
Also fix a wrong alignment on struct and sync the comment with the one
in ChromeOS EC codebase.
Fixes: dff08caf35ec ("platform/chrome: cros_ec: Add command for regulator control.")

The original numbers were chosen before the 0x012B is used in ChromeOS
EC codebase. Since the original kernel patch got accepted before the
corresponding commit in ChromeOS EC codebase got merged, the host
command number was used by other commit first.
Since now the commit in ChromeOS EC codebase
(https://crrev.com/c/2247431) with updated host command numbers got
merged, need this patch to sync up the host command numbers with
ChromeOS EC codebase. Sorry for the confusion.

This needs to go through Mark Brown's regulator tree as depends on
dff08caf35ec, if not, I can pick as a fix when the next merge window is closed.

Ups, next time we need to make sure the EC code lands before.

Applied to

Thanks!
[1/1] platform/chrome: cros_ec: Fix host command for regulator control.
commit: a233547660a3915973d41e2a9a0923d0cf317a62
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
