[PATCH] Updated tick implementation for HAL_GetTick

[Robin Müller]

Hmm, do you have an idea how to fix this cleanly? Was this the reason the
implementation returned 0?
This was not an issue with the other implementation:

(rtems_clock_get_ticks_since_boot() * 1000) /
rtems_clock_get_ticks_per_second();

Kind Regards
Robin
