[Qemu-devel] [RFC 1/2] ahci: Refactor ports as a fixed-size array for VMState

["Andreas Färber" <afaerber@suse.de>]

It seems, VMState cannot handle a dynamically allocated array of
structs at this time.

Change AHCIState to use an AHCIDevice array of size AHCI_MAX_PORTS.
Of those 32, only 6 are being used for ich9.
