stm32/octospi: Add OSPI support for STM32H7 MCUs.

Browse Source 
Added a if-statement to `octospi.c` to detect if the targeted MCU is one of
the STM32H7 series.  If that is the case, another set of variables are used
for the `mp_hal_pin_config_alt_static_speed()` function, as well as for
register `OCTOSPI1->CR`.  This allows the STM32H723 and STM32H7B3 series
MCU to use octo-spi flash like the STM32H573 series MCU.
