kernel: Disable IRQ time accounting

Browse Source 
This feature is now disabled (was disabled on ARM before) as we do not
need it:

"Select this option to enable fine granularity task irq time accounting.
This is done by reading a timestamp on each transitions between softirq
and hardirq state, so there can be a small performance impact."
