This reverts commit a4e51f3942.
This commit led to more errors on the first IMU on a normal
CubeBlack. I don't yet know why this happens, but I'm removing this in
master for now as it affects primary IMU
This aims to fix#11455. I have been unable to reproduce the issue,
which leaves me thinking it is either a bootloader difference or a hw
difference between pixhawk1 clones and real pixhawk1 boards
then enable after 100ms, and let settle for 20ms. This is to fix an
issue with peripheral power on consistency with all fmuv3 boards
Thanks to Philip for the suggestion
this uses the ChibiOS system timer instead of a separate GPT timer for
the core ChibiOS timer. The advantage is it saves us a timer, plus it
changes ChibiOS to use a 1MHz clock on its timer, which gives us
higher resolution for delays.
This has a remarkable effect on timing jitter, reducing it greatly
