TTY fix for 6.10-rc2
Here is a single revert for a much-reported regression in 6.10-rc1 when it comes to a few older architectures. Turns out that the VT ioctls don't work the same across all cpu types because of some old compatibility requrements for stuff like alpha and powerpc. So revert the change that attempted to have them use the _IO() macros and go back to the known-working values instead. This has NOT been in linux-next but has had many reports that it fixes the issue with 6.10-rc1.
