bsps/stm32h7: add configuration and enable build of stm32h757i-eval BSP

This is minimalist configuration for the stm32h757i-eval BSP provided
here. The only general enhancement worth mention is boot core
configuration which is needed here as this is the first dual-core board
supported by stm32h7 BSP family and we need to choose boot core in order
to get C files compiling well.
