If the AHCI ports' HPCP or ESP bits are set, the port

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.

Applied to libata/for-4.4. Let's see what happens.
Ugh. Yet another revert to include in my own builds, I guess.
eSATA is used for permanent storage expansion with port-multipliers,
and having to stop command queuing frequently for useless polling
is gonna be a performance drain.
