mali_kbase: hold GPU utilization for premature update.
The GPU internal counter is updated every IPA_CONTROL_TIMER_DEFAULT_VALUE_MS milliseconds.
If an utilization update occurs prematurely and
the counter has not been updated, the same counter
value will be obtained, resulting in a difference
of zero.
To handle this scenario, this change will skip the
utilization update if the counter difference is zero
and the update occurred less than 1.5 times the internal
update period (IPA_CONTROL_TIMER_DEFAULT_VALUE_MS).
