support for display Liligo-T Display (ST7789 TFT) lost after upgrade to 15.2 or 15.3

### PROBLEM DESCRIPTION
_A clear and concise description of what the problem is._
I have been flashing  a TTGO Display (ESP-32) with tasmota32-display.bin 15.1, used the Auto-config and selected the Liliygo-T-Display configuration. The process created a working display.

After upgrading to 15.2 or 15.3 using the OTA Url upgrade, I can not change any display content any more.

The display still shows the last message from before the upgrade process.
Reverting back to 15.1.0 always gives back the working display functionality.
