What I mean is if we still use global variable for base address, but
still need this externs.

Do you move reset bridge code to drivers/reset as well?
Do you use global variable too after get struct udevice instance or
get again device instance every time when need it?

If we don't want to add global variable to .data section, then we need
convert all those drivers to DM for Gen5/A10/S10 as you did for Gen5.
Otherwise, we can't get Agilex series patchset get merged to mainline,
because it depends on this series.
