x86/ioapic: Cleanup IO/APIC route entry structs
Having two seperate structs for the I/O-APIC RTE entries (non-remapped and
DMAR remapped) requires type casts and makes it hard to map.
Combine them in IO_APIC_routing_entry by defining a union of two 64bit
bitfields. Use naming which reflects which bits are shared and which bits
are actually different for the operating modes.
[dwmw2: Fix it up and finish the job, pulling the 32-bit w1,w2 words for
register access into the same union and eliminating a few more
places where bits were accessed through masks and shifts.]
