ata: ahci: find eSATA ports and flag them as removable
If the AHCI ports' HPCP or ESP bits are set, the port should be considered external (e.g. eSATA) and is marked as removable. Userspace tools like udisks then treat it like an usb drive. With this patch applied, when I plug a drive into the esata port, KDE pops up a window asking what to do with the drives(s), just like it does for any random USB stick. Removability is indicated to the upper layers by way of the SCSI RMB bit, as I haven't found another way to signal userspace to treat a sata disk like any usb stick.
