Fixing the functionality of IRQs 0-15?

[christian-herber-nxp]

In CLINT mode, are reserved for special interrupt sources like software and timer interrupts. CLIC specification has this section:

Does it make sense to prepare the IP for those configurations? Seems very realistic to me one would adopt those.

I consider both #13 and #14 a prerequisite to fixing the issue mentioned here. It allows

• following the recommendation to reserve certain interrupts
• allowing the implementation of SW interrupts (mode=edge, interrupt signal tied to 0)
