ata: ahci: Add Green Sardine vendor ID as board_ahci_mobile

AMD requires that the SATA controller be configured for devsleep in order for S0i3 entry to work properly. commit b1a9585 ("ata: ahci: Enable DEVSLP by default on x86 with SLP_S0") sets up a kernel policy to enable devsleep on Intel mobile platforms that are using s0ix. Add the PCI ID for the SATA controller in Green Sardine platforms to extend this policy by default for AMD based systems using s0i3 as well.
