This looks great and a cherry-pick candidate if you agree?

Just wondering, was there a name conflict for shorter VAPIC()?
It's file-local, so doesn't really matter.

Np, BTW I have a second similar clean-up in v2 for IOAPIC

Nope, I just followed *_DEVICE model like for SYS_BUS_DEVICE()

Okay, then let's avoid unnecessary _DEVICE in your upcoming resend. The
only other place for actual devices where I remember we needed it was to
distinguish between PCI host bridge and its PCI device representation on
the bus. There is also no "Device" in the struct name.
