plugins/sed: add sid password change

[gjoyce-ibm]

The existing ioctl to change password only updated the admin1 password. Add using a new ioctl IOC_OPAL_SET_SID_PW to also update the sid password so that sid and admin1 passwords are kept in sync.

Looks good to me. Let's wait until the matching kernel code has been merged.

I might have missed the kernel change, is this still the last version:

Yes. That's the last version. No code changes but I added to the description and added a reference to this pull request.

In three weeks there have been no comments on the resend.

I'll bring this up at Linux Plumbers or at Alpss next week. Let's see if this helps.

Any discussions?

Yes I discussed it with Keith and he was somewhat familiar with the protocol. I was not able to remember the details why this is necessary but he said he didn't really mind the change though, IIRC.

Let me ping him again here, @keithbusch would you mind to queue up or review these patches: https://lore.kernel.org/all/[email protected]

Thanks!
