33d9ff5985 microblaze: Fix level interrupt ACKing
Level interrupts need to be ack'd in the unmask handler, as in powerpc.
Among other issues, this bug causes the system clock to appear to run at
double-speed.

892ee92b81 microblaze: Sane handling of missing timer/intc in device tree
This code path doesn't test any returned pointers for NULL, leading to a bad
kernel page fault if there's no timer/intc found.

Slightly better is to BUG(), but even better still would be a printk beforehand.
