Bikeshed:
While doing all this, I think put/get irq is really terribly named. I
was a much bigger fan of the enable disable.

Also, you could use a bit of flow control to write to the correct IMR
register and not duplicate functions at all. You already do the
POSTING_READ so performance shouldn't matter.

Something like...

uint32_t imr = GEN(dev) >= 5 ? GTIMR: IMR;
