add new CUAV Nora board

[bkueng]

Rebased version of #14272.

@CUAVcaijie can you test this? I added some changes in abe16d7.

TODO:

• add to CI
• adis16470 driver
• icm20649 driver

Hi @bkueng You guys got a plan to add docs for this board?

[ShiauweiZhao]

重新定位的版本 ＃14272。
@CUAVcaijie你可以测试吗？我在abe16d7中添加了一些更改。
去做：

• 添加到CI
• adis16470驱动程序
• icm20649驱动程序

when I use CUAV Nora to debug ADIS16470, when I use int SPI :: transferhword (uint16_t * send, uint16_t * recv, unsigned len) function, the program is stuck.

hard fault?

It is possible that the H7 library does not yet support 16-bit SPI transmission

The board has been added already. Can this be closed?

Yes, although one missing piece in master is still supporting all 14 PWM. Let's bring that in separately.
