[BUG] pin postprocessing destroys SPI CS pins

[FGSikasa]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

setting in configuration.h
#define X_DRIVER_TYPE TMC26X
#define Y_DRIVER_TYPE TMC26X
#define Z_DRIVER_TYPE TMC26X

With the above setting:
The STEP_PINs, DIR_PINs and ENABLE_PINs are set properly but the postprocessing in pin_postprocess.h sets the CS_PINs to -1.

//
// Destroy unused CS pins
//
#if !AXIS_HAS_SPI(X)
#undef X_CS_PIN
#endif
#if !AXIS_HAS_SPI(Y)
#undef Y_CS_PIN
#endif
#if !AXIS_HAS_SPI(Z)
#undef Z_CS_PIN
#endif

Is it possible to disable the E_Stepper, the Heater and the temperature sensor ?

I would like to test only the X, Y and Z Steppers.

macro AXIS_HAS_SPI( axis ) fails to identify that TMC26X uses SPI

Fixing the macro is easy, but shows more issues...
