[BUG] Building with GCC14 and C++23 causes 'volatile-qualified left operand' warnings

[bmourit]

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

Yes, and the problem still exists.

Bug Description

I have a patch to fix the warnings prepared as well, so this bug report is just to track that. Fairly simple, just two places in the planner.h.cpp files.

Bug Timeline

Introduced when building with newer GCC and C++ standards

Expected behavior

No warnings, and remove the need for using -Wno-volatile for the GD32 platform.

Actual behavior

Two instances of the warning are generated:
"warning: using value of assignment with 'volatile'-qualified left operand is deprecated [-Wvolatile]"

Steps to Reproduce

Remove the flag -Wno-volatile from the gd32.ini file and build a GD32 board.

To save you some time, you can skip creating a bug report if you already have a patch / PR ready to go.
