arch/xtensa: xtensa_intgen.py: Emit handlers for all levels
The original code would (unsurprisingly) only emit handler functions
for interrupt levels with interrupts associated with them. But it
turns out that it's possible to configure an xtensa device with an
empty-but-otherwise-real interrupt level (specifically mt8195 has a
"Level 3" interrupt not associated with any input IRQS, it's one level
above EXCM_LEVEL and one level below the DEBUG exception).
This script is old, and not set up to parse the full core-isa.h
directly, so modifying it to detect this condition is difficult.
Instead, just emit all 15 possible interrupt handlers, even empty
ones. The extra stubs are harmless as they'll be dropped if uncalled.
