Add error if OS tickrate is changed 

The current mbed-os drivers rely on a tickrate of 1ms for timing.
This means that if OS_TICK_FREQ is set to any value other than 1000
then mbed-os driver will no longer delay for the correct amount of
time. To prevent this from happening this patch triggers a compile
time error if a tickrate other than 1m is used.
