[2.0.x] Update to TMC2208Stepper 0.2.5

[thinkyhead]

The TCM2208Stepper library has been updated to 0.2.5, with support for software serial on the LPC1768 platform.

@teemuatlut — Are there other changes I need to make? Getting these errors.

You're testing TMC2208 with SW serial on platforms that don't support it.
Either drop TMC2208 tests on them, or set the test to use HW serial.

I'd also suggest this to be added to SanityCheck.h

/**
 * TMC2208 software UART is only supported on AVR and LPC1768
 */
#if HAS_DRIVER(TMC2208) && !(defined(__AVR__) || defined(TARGET_LPC1768)) && !( \
       defined(X_HARDWARE_SERIAL ) \

    || defined(Y_HARDWARE_SERIAL ) \

#endif

You're testing TMC2208 with SW serial on platforms that don't support it.

I didn't alter the Travis CI tests for any platforms, but only specified that 0.2.4 should be used (also for LPC1768) in the .ini file. So Travis CI should be doing exactly the same tests for 0.2.4 as it was doing for 0.2.3. The errors simply don't occur with the previous version of the library. Did the default behavior change in some way?

I'd also suggest this to be added to SanityCheck.h

That was already done.

v0.2.4 hides the SW serial constructor of the library when used with platforms that are not supported with a SW serial library.

Almost…

Once the library version is updated to 0.2.5 I will restart the Travis CI tests and expect them to pass.
