As noted in #130 allen key probe stow rate is based on homing rates,
but homing rates were left out of most delta configs. This unifies the
XYZ homing rates and applies the unified rates to allen key movements.

As noted in #133 you can’t disable `SDSUPPORT` with `MAKRPANEL`,
`PANEL_ONE`, `MINIPANEL`, or `ULTIPANEL`. This patch makes it possible

default.

Users of these controllers will now need to enable `SDSUPPORT` in their
configurations as others currently do.
