SERV. It can be set to MINI for the default behaviour, or NONE to
only apply reset where absolutely needed and rely on POR to clear

40000cbeb9 Fix IRQ 
This contains a lot of fixes as IRQ support was broken on both
RTL and zephyr side

* Interrupts are now synced to instruction lifetimes
* Interrupts are disabled on traps and mie is pushed to mpie
* Zephyr applications regenerated from rewritten Zephyr port
* Timer is 32-bit to avoid wrapping around too often
* MEPC was not read properly from CSR storage
