Hi, all

I would like to start working on developing support for STM32H735 
microcontrollers in NuttX OS, but I found some strange things in the principle 
of configuring this series of microcontrollers.

Microcontrollers of the H7 series are divided into several subseries, each 
united by one reference manual:
    - STM32H723/733, STM32H725/735 and STM32H730 (RM0468)
    - STM32H745/755 and STM32H747/757 (RM0399)
    - STM32H742, STM32H743/753 and STM32H750 (RM0433)
    - STM32H7A3/7B3 and STM32H7B0 (RM0455)

But some header files in arch/arm/include/stm32h7 are designated as 
stm32h7x3xx_irq.h or stm32h7x5xx_irq.h, although they are only for the H743 or 
H745 series respectively, not for H723 or H735. And such a discrepancy is also 
present in other source code files that belong to the H7 series.

Maybe it's worth fixing this somehow? Will this break anything important?
