arch-stm32f7/stm32.h file is shared between STM32F746 and STM32F769 MCUs. But STM32F769 embeds 2MB of internal flash instead of 1MB for STM32F746. The flash layout is quite similar between the 2 SoCs :
STM32F746 STM32F769 4 * 32KB sectors 4 * 32KB sectors 1 * 128KB sector 1 * 128KB sector 3 * 256KB sectors 7 * 256KB sectors
Update sect_sz_kb[] structure and SYS_MAX_FLASH_SECT accordingly.

Changes in v2:
- Remove SYS_UBOOT_FLAG from stm32f746-disco.h
