Kernel: Simplify PCI::MMIOAccess segment storage
Instead of nesting a bunch of heap allocations, just store them in a simple HashMap<u16, MMIOSegment>. Also fix a bunch of double hash lookups like this: ASSERT(map.contains(key)); auto thing = map.get(key).value(); They now look like this instead: auto thing = map.get(key); ASSERT(thing.has_value());
