arc: remove defaults for IRQ priority levels

Browse source 
The deleted defaults cannot be overriden by defaults defined
in SoC's Kconfig file. The number of IRQ priority level was
always one, and this caused some code to be dropped within
the fast IRQ handling code. When the electrons aligned in
certain way, undesired effects were observed (e.g. exception,
faults, etc.) when regular IRQs were mixed with fast IRQs.

Moreover, ARC cores are high configurable on hardware level.
So let the SoC config define these values instead.
