Fix #14045

- Fix the `fsmc` and `sdio` units which required hard defines for use.

- Can generally boost the allowed output power (for hotbed,nozzle and fans).

Partially undo 15357af6 to ensure TMC code is initialized in the proper order.

Low or unknown probe clearance on init (even at powerup) is a risk and therefore, a deploy should be avoided because dragging the pin is possible: A deploy goes into alarm if it can't extend fully and then the subsequent stow will fail.
