* CF/BF - Update DSP_Lib and STM32F7/Drivers/CMSIS to CMSIS 5.3.0.
CMSIS 5.3.0 - https://github.com/ARM-software/CMSIS_5/releases/tag/5.3.0
* cleanup lib.
* pfft
* relocate driver files from lib/main/CMSIS/CM* to lib/main/STM32xx
folders
* Move DSP folder inside CM5.
It came from the same source as the other files inside CM5
* Remove the CM5 folder and move the files in it one level up.
* CF/BF - Set STM32F7 SPI FAST clock to 13.5Mhz - Gyros not stable at
27mhz.
* CF/BF - Initial SPRacingF7DUAL commit.
Support two simultaneous gyro support (code by Dominic Clifton and Martin Budden)
There are new debug modes so you can see the difference between each gyro.
Notes:
* spi bus instance caching broke spi mpu detection because the detection
tries I2C first which overwrites the selected bus instance when using
dual gyro.
* ALL other dual-gyro boards have one sensor per bus. SPRacingF7DUAL is has two per bus and thus commit has a lot of changes to fix SPI/BUS/GYRO initialisation issues.
* CF/BF - Add SPRacingF4EVODG target.
This target adds a second gyro to the board using the SPI pads on the back of the board.
* CF/BF - Temporarily disable Gyro EXTI pin to allow NEO target to build.
