[BUG] Z_MAX endstop is not operational in MKS_ROBIN_NANO_v1v2

[bkiziuk]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I moved from some older bugfix-2.0.x to the current bugfix-2.1.x branch.
I found out that the printer does not respect Z_MAX endstop which was used during Z_HOMING process to ensure that (because of a need to provide clearance for Z_PROBE) the bed will not be lowered beyond the physical machine limits.

Bug Timeline

No information since I've stopped to use newer versions of bugfix-2.0.x and jumped in to the recent bugfix-2.1.x

Expected behavior

When hitting Z_MAX endstop during homing, the bed should stop moving down, but the process of homing should not be interrupted.

Actual behavior

The Z_MAX endstop is not triggered.
The M119 command does not list Z_MAX endstop at all.

Steps to Reproduce

1. Initiate Z_HOMING
2. press the Z_MAX endstop while the bed moves down

Is meant to be addressed here #25758 with Z_SAFETY_STOP
