hw/ide/ahci: Move allwinner code into a separate file
The allwinner code is only needed for the allwinner board (for which we also have a separate CONFIG_ALLWINNER_A10 config switch), so it does not make sense that we compile this for all the other boards that need AHCI, too. Let's move it to a separate file that is only compiled when CONFIG_ALLWINNER_A10 is set.
