cyclic: doc: Update documentation for CONFIG_CYCLIC_MAX_CPU_TIME_US

Browse Source 
Cyclic now just print a warning once instead of disabling the cyclic
function when the cyclic function upon exceeding CPU time usage.

Fixes: ddc8d36a74 ("cyclic: Don't disable cylic function upon exceeding CPU time")

blinking etc. The functions that are hooked into this cyclic list should
be small timewise as otherwise the execution of the other code that relies
on a high frequent polling (e.g. UART rx char ready check) might be
delayed too much. To detect cyclic functions with a too long execution
time, the Kconfig option `CONFIG_CYCLIC_MAX_CPU_TIME_US` is introduced,
which configures the max allowed time for such a cyclic function. If it's
execution time exceeds this time, this cyclic function will get removed
from the cyclic list.

time, the Kconfig option `CONFIG_CYCLIC_MAX_CPU_TIME_US` was introduced.
It defines the maximum allowable execution time for such a cyclic function. The
first time the execution of a cyclic function exceeds this interval, a warning
will be displayed indicating the problem to the user.
