ahci: fix sysbus support
Non-PCI AHCI support is broken due to assertion failures when trying
to convert AHCIState to a PCIDevice pointer as AHCIState can have
different container structs. Fix this by using the non-asserting object
cast and checking the returned pointer is not NULL.
The AddressSpace pointer is also being initialized to NULL and causing
dma_memory_map call to fail. Fix this by initializing to
address_space_memory for sysbus instances.
Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState
for sysbus instances.
