This is only for allocating the port IO address range.
If a platform does not have PIO devices at all, the address
range will simply be unused.
So, simplify the vm-allocator data structure by making both
MMIO and PIO mandatory.

The IO memory alignment should be set as byte alignment instead of 0x400
which is copied from crosvm.

This is based on the crosvm resource allocator from commit 107edb3e.
We only have PIO and MMIO address space to handle, and don't have a GPU
specific path and space.
Also, we support allocating a range at a specified address. This is
mostly useful for PIO, but might be also necessary for MMIO.
