Fix SKR Mini - BTT TFT Simulation mode display #1021

Figured out why I couldn't get the little simulation mode to render. BTT's TFT appears to only accept an active low clock signal. Changed the SPI mode only for STM32F1's inside u8g2's st7920 display info.

The st7920 is in deed very picky on timings. Took me a while to get timings that worked with the due.

Definitely. Hopefully the timings needed are all the same across other users with it.
