    arm/armv7-[a|r]: move fpu save/restore to assembly handler

    Save/Restore FPU registers in C environment is dangerous practive,
    which cannot guarantee the compiler won't generate the assembly code
    with float point registers, especially in interrupt handling

bb10e0fc25 Add support for STM32G474: Add B-G474E-DPOW1 board
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:
