STM32: Add Flash API support to STM32F413xH
First add the flash_data.h that describe the flash memory topology, and also activate FLASH support for the corresponding targets. This is a 1,5MB flash memory device which contains 15 sectors, where sectors 12 to 15 are 128KB sectors. So flash_api.c needed has been updated to differentiate between this flash memory and the 2MB ones by checking existence of sector 16 instead of sector 12.
