intpm: minor issues in debug printing

[Andriy Gapon]

I've recently performed some hacking of SMBus-attached peripherals in 
PIIX4-based system and I haven't always been nice to the bus. While 
doing that I noticed two very minor issues with printing in intpm.c.
I got "mysterious" messages like the following:
unknown: unknown cause why?
[Two "unknowns" is too much :-)]
The attached patch should fix that.
