dts: silabs: interrupt levels corrected
Downgrading interrupt priority for non critical interrupts for the supported SOCs. Previously almost all interrupts were at level 0 i.e. meaning no interrupt had priority over the others. In reality only radio interrupts are critical while others can be served with less haste. Now the level zero is reserved for interrupts that need higher priority than the radio without bypassing irq locks (zero-latency interrupts) Level 1 for radio and levels 2 and 3 for rest of the services.
