sata: ahci-da850: implement a workaround for the softreset quirk
There's an issue with the da850 SATA controller: if port multiplier support is compiled in, but we're connecting the drive directly to the SATA port on the board, the drive can't be detected. To make SATA work on the da850-lcdk board: first try to softreset with pmp - if the operation fails with -EBUSY, retry without pmp.
