Struct seed_riscv::memory::MemoryManager

pub struct MemoryManager(Spinlock<MemoryManagerInner>);

The physical memory manager - this consumes a MemoryRegions map, and uses it to initialise an instrusive free list of all usable physical memory. This can then be used to allocate physical memory as needed, at frame granularity.
