MK2_MULTIPLEXER does not require E2/E3 stepper pins

[2.0.x] Followup for MESH_EDIT_GFX_OVERLAY

[2.0.x] Implement NANODLP_Z_SYNC for 2.0.x

These changes may need to be warmed over.  I tried to fix things with
the least amount of disruption.   I just wanted to get the bugfix_v2.0.0
branch working for people again.

[2.0.x]  Adapt G26 to work for all meshes

[2.0.x] Tool change bad behaviour fix

Previous fix did not work as expected when axeis not homed. It raise Z but never return to original position

[2.0.x] Add BIQU BQ111-A4 board

[2.0.x] Fix up LCD init / charset

[2.0.x] Add support for Ultratronics Pro v1.0 and fix compiling for Due HAL

[2.0.x] LP1768 - fix PWMs

Followup to 13a3fb1acc

[2.0.x] General code clean/comment

Can LCD shift registers keep up with faster MCUs?

Remove pin count check for MIGHTYBOARD_REVE

Remove assert and unused code since it is implemented in pinsDebug_plus_70.h

[2.0.x] tool change bad behaviours

This will solve 2 issues on tool change.
1) when no home is done ("no_move" is set) tool change should never move X & Y because... I don't know where I am...only Z should be adjusted to avoid bed collision if other nozzle is lower than current.
Since no move no bed level matrix should be applied
2) When SWITCHING_NOZZLE is enabled and system is homed there are two movements to go to destination, but first can move Z to older position and then crash on the bed

Update pins_RuRAMPS

Add and bugfix pins

[2.0.x] Updates to Anet A8 configurations
