Move the v3 resource allocator to v2.
Major changes:
1. Separate resource allocation into:
A. Read Resources
B. Avoid fixed resources (constrain limits)
C. Allocate resources
D. Set resources
Usage notes:
Resources which have IORESOURCE_FIXED set in the flags constrain the placement
of other resources. All fixed resources will end up outside (above or below)
the allocated resources.
Domains usually start with base = 0 and limit = 2^address_bits - 1.
I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is
still there for resources. Some platforms may want to change that, but I didn't
want to break anyone's board.
Resources are allocated in a single block for memory and another for I/O.
Currently the resource allocator doesn't support holes.
