Add support for the STM32G474 family of microcontrollers and the
B-G474E-DPOW1 Discovery Board, which features a STM32G474RET6.
This is a major pull request as it adds support for an entirely
new family of STM32. This support is implemented in
arch/arm/src/stm32 and shares implementation with other STM32
families supported by that code, such as the 'L15xx, 'F10xx,
'F20xx, 'F3xxx, and 'F4xxx.
boards/Kconfig:
* Make NuttX recognize the existence of b-g474e-dpow1,
the B-G474E-DPOW1 Discovery Board.

* Add minimal support for the B-G474E-DPOW1 Discovery
Board. The board boots successfully through to the
NSH prompt. NSH runs and is responsive.
With big thanks for detailed code review and suggestions:
