With LPID width plumbed through from firmware, LPID allocations can now be dynamic, which requires changing the fixed sized bitmap. Rather than just dynamically sizing it, switch to IDA allocator.
Nested KVM stays with a fixed 12-bit LPID width for now, but it is also moved to a more dynamic allocator. In future if nested LPID width is advertised to a guest it will be simple to take advantage of it.
