[bugfix-1.1.x] 'TMC2208Stepper' does not name a type

[yagona]

Description

Setup:

• modified Anycubic i3 Mega
• TMC2208 at X,Y,Z,Z2 are in legacy mode (STANDALONE)
• TMC2208 at E0 is connected via SoftwareSerial RX/TX to be used in hybrid mode

Since the simplified stepper driver configuration was introduced, my configuration fails to compile successfully.

Steps to Reproduce

I could identify three representative tests to indicate the issue:

[Test 1] wanted configuration

Configuration.h:

define X_DRIVER_TYPE TMC2208_STANDALONE

define Y_DRIVER_TYPE TMC2208_STANDALONE

define Z_DRIVER_TYPE TMC2208_STANDALONE

define Z2_DRIVER_TYPE TMC2208_STANDALONE

define E0_DRIVER_TYPE TMC2208

=> compilation error:

stepper_indirection.h:300: error: 'TMC2208Stepper' does not name a type extern TMC2208Stepper stepperE0;

[Test 2] add another TMC2208 though not connected

Configuration.h:

define X_DRIVER_TYPE TMC2208

define Y_DRIVER_TYPE TMC2208_STANDALONE

define Z_DRIVER_TYPE TMC2208_STANDALONE

define Z2_DRIVER_TYPE TMC2208_STANDALONE

define E0_DRIVER_TYPE TMC2208

=> compilation successful

[Test 3] force library to be included

Configuration.h:

define X_DRIVER_TYPE TMC2208_STANDALONE

define Y_DRIVER_TYPE TMC2208_STANDALONE

define Z_DRIVER_TYPE TMC2208_STANDALONE

define Z2_DRIVER_TYPE TMC2208_STANDALONE

define E0_DRIVER_TYPE TMC2208

stepper_indirection.h: //#if HAS_DRIVER(TMC2208)

include

void tmc2208_serial_begin(); void tmc2208_init_to_defaults(); //#endif

=> compilation successful

Expected behavior: [compilation successful for Test 1]

Actual behavior: [compilation fails when E0 is the only TMC2208 and others are in STANDALONE mode]

This is another case of drivers.h included before Configuration_adv.h, as it should be. But it also means they can't both depend on the other. driver.h should not depend on any settings from Configuration_adv.h.
