EXP1 and EXP2 are mirrored

[RobTS]

After spending plenty of time trying to get one of your 12864 displays connected, I have figured out the reason: The mapping of EXP1 and EXP2 (and possibly EXP3 too, haven't checked) is inverted (e.g. 1 is 10, 10 is 1, and so on). When trying to set up your 12864 according to the default klipper config for lcds, this leads to klipper not being able to run due to errors such as pin EXP1_3 is reserved for <RST> preventing startup. When invering the pin headers, the display starts working flawlessly.

@RobTS do you happen to have your fixed config? Do you mind sending it here?
