boards/arm: stm32h747i_disco_m7: Enabling flash support in device tree. 

This commit enables flash support for stm32h747i_disco_m7
in device tree. This has been tested with flash sample
application on stm32h747i_disco platform with m7 core.

Flash is shared between two cores (M4 & M7) so the last 1M is
assigned to M4 core. Hence allocating 1M of storage at the
end of first 1M.
