NUCLEO=STM32H745ZI-Q: problems with SPI1 and SPI3

I have also tried it like so:

Looks like a C/C++ error. In debug mode the C compiler will initialize variables (non-standard behaviour) while the C++ compiler will not. Of course, I am trying to write some ordered C++ code here, which STM32CubeIDE is not too good at.

The problem was with `hspi` handles; solved by initializing them:

LCD_Nokia_5110::LCD_Nokia_5110() :
	hspi1({0}),
	hspi3({0})

Not having been zeroed, hspi.State was something else than 0 (HAL_SPI_STATE_RESET) and so ` HAL_SPI_MspInit(hspi);` would not get called any more.

These HAL_MSP* callbacks are yet another pain in the game, I did not realize those contained useful code...

I must say that in anticipation to the horrors of this Eclipse based ugliness I spent some 3-4 days trying to port this board in `mbed` and failed. Supporting it there would be much appreciated.
