Added a flash driver for the STM32G4 series. The primary change here is the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash driver as a template. The primary difference is the accounting for dual banks with different page sizes for category 3 flash devices. For category 3 devices, flash page size and number of pages is determined at runtime. Added additional configuration information to hardware/stm32_flash.h for all supported STM32G4 devices. *Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary No flash driver existed previously for the STM32G4 family. This commit adds flash support for the STM32G4. Flash support includes defining functions provided by the progmem interface, as well as adding some generic flash_lock, flash_unlock, and stm32_flash_user_optbytes. ## Impact This commit should only impact the chips in the arch/arm/src/stm32 category. More specifically, only STM32G4 chips should be impacted within that category. ## Testing Tested with a Nucleo-G474RE Development Board. Tested by calling each public function provided by stm32g4xxx_flash.c during bringup. Each function was called with varying inputs and verified the correct outcome was achieved after each call. Also tested by creating a mtd config device "/dev/config" with mtd_config and mtd_progmem. I was able to read from the /dev/config device successfully. Lastly, I tested building nuttx with other architectures and chips to make sure nothing unexpected was broken. -- This is an automated message from the Apache Git Service.
