[PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]

Currently, the only per-dev EH action is REVALIDATE.  EH used to
exploit ehi->dev to do selective revalidation on a ATA bus.  However,
this is a bit hacky and makes it impossible to request selective
revalidation from outside of EH or add another per-dev EH action.

This patch adds per-dev EH action mask eh_info->dev_action[] and
update EH to use this field for REVALIDATE.  Note that per-dev actions
can still be specified at port-level and it has the same effect of
specifying the action for all devices on the port.
