Move HAL_Init call for F3/F4/F7/H7.

* HAL_Delay() was being used before HAL_Init() was called.
* Brings it in-line with ST examples which follow this call order:
CubeMX generated code goes startup_xxx.s (asm) -> SystemInit(), then
main(), HAL_Init(), SystemClock_Config()

Boot-tested on:
* SPRacingF4NEO
* SPRacingF7DUAL
* SPRacingH7ZERO
