Extended programming operations functions

==============================================================================
                 ##### Flash Extension features #####
==============================================================================

[..] Comparing to other previous devices, the FLASH interface for STM32F427xx/437xx and
     STM32F429xx/439xx devices contains the following additional features

     (+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
         capability (RWW)
     (+) Dual bank memory organization
     (+) PCROP protection for all banks

                    ##### How to use this driver #####
==============================================================================
[..] This driver provides functions to configure and program the FLASH memory
     of all STM32F427xx/437xx, STM32F429xx/439xx, STM32F469xx/479xx and STM32F446xx
     devices. It includes
    (#) FLASH Memory Erase functions:
         (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
              HAL_FLASH_Lock() functions
         (++) Erase function: Erase sector, erase all sectors
         (++) There are two modes of erase :
           (+++) Polling Mode using HAL_FLASHEx_Erase()
           (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()

    (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
         (++) Set/Reset the write protection
         (++) Set the Read protection Level
         (++) Set the BOR level
         (++) Program the user Option Bytes
    (#) Advanced Option Bytes Programming functions: Use HAL_FLASHEx_AdvOBProgram() to :
     (++) Extended space (bank 2) erase function
     (++) Full FLASH space (2 Mo) erase (bank 1 and bank 2)
     (++) Dual Boot activation
     (++) Write protection configuration for bank 2
     (++) PCROP protection configuration and control for both banks
