stm32h7 RTC and friends  support

* stm32h7:Removed f7 in file path

* stm32f7:Fix overwritten IRQ enabled

       System boot order calls clock_initialize then up_initalize.
       clock_initialize was setting up the alarm IRQ
       up_initalize is initializing the NVIC.

       This most likely worked in the past due to a bug in the
       NVIC init code that failed to clear the Interrupt enables.
       That was fixed in 510b0f7e arch/arm/src: Correct all ARMv7-M
       architectures.  Interrupts were not be disabled correctly
       on power up.

* stm32h7:Ported over F7 RTC

* nucleo-h743zi:Add RTC
