Add support for 2.25" ST7789 76x284 TFT.

Hi!

I added support for 2.25" ST7789 76x284 TFT.

It is this one:

Without this change I only see noise and sometimes an update depending on the orientation. I figured out this display needed column and row offsets, which appear to be 82 and 18.

This seems relevant to know:

  -DST7789_DRIVER=1
  -DTFT_WIDTH=76
  -DTFT_HEIGHT=284

I tested with all 4 rotations.

Here is the test project that runs in the screenshots: https://github.com/atoomnetmarc/ST7789-76x284

+1 for this PR
Maybe (somewhere) with the little info: BL Pin must be set to GND not to VCC (like on most of all other display modules)

This is working for me too - please consider pulling it in!

I can confirm this works for me too, same LCD model ST7789p3, size is 76x284.

Works great. Thanks @atoomnetmarc for your help. I love this display and was happy to find your PR.
Please merge it in - so others could also use it

Has worked for me too for this display (https://www.aliexpress.com/item/1005008937314193.html). I worked out the inverted backlight, inverted display and RGB colour order, but I wouldn't have worked out those offsets, thanks for the commit!
