focus on affective changes

Changes to SPI in #27392 break Lulzbot TFT SPI communication. Reverting the changes to this file restore operation.

Cardreader changes need investigation, as with these changes machine will boot loop with USB inserted.  Removing the usb at boot, then inserting after init allows it to complete. Does not occur with all changes from this the origin PR reverted.

+ * Peltier Bed - Heating and Cooling
+ *
+ * A Peltier device transfers heat from one side to the other in proportion to the amount of
+ * current flowing through the device and the direction of current flow. So the same device
+ * can both heat and cool.
+ *
+ * When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
+ * side, the dissipated power (voltage * current) must also be rejected. Be sure to set up a
+ * fan that can be powered in sync with the Peltier unit.
+ *
+ * This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
+ * well without filter circuitry.
+ *
+ * Since existing 3D printers are made to handle relatively high current for the heated bed,
+ * we can use the heated bed power pins to control the Peltier power using the same G-codes
+ * as the heated bed (M140, M190, etc.).
+ *
+ * A second GPIO pin is required to control current direction.
+ * Two configurations are possible: Relay and H-Bridge
+ *
+ * (At this time only relay is supported. H-bridge requires 4 MOS switches configured in H-Bridge.)
+ *
+ * Power is handled by the bang-bang control loop: 0 or 255.
+ * Cooling applications are more common than heating, so the pin states are commonly:
+ *   LOW  = Heating = Relay Energized
+ *   HIGH = Cooling = Relay in "Normal" state

+     * before triggering a filament change. This leaves some filament in the

+     * filament change. But this can cause problems as a little bit of filament
+     * will be left between the extruder gears (thinking that the filament
