Hi Andreas,

Zephyr uses GitHub pull requests for contributions:

You probably want to submit this as a PR instead.

This change fixes the prescaler values in the defconfig. The prescaler values
shown in the technical reference manual (STM32F407xx, p.19) differ from those in
the defconfig which results in wrong timer delays.
