SCSI midlayer has moved hostt->eh_timed_out to transport template. As
libata doesn't need full-blown transport support yet, implement
minimal transport for libata. No transport class or whatsoever, just
empty transport template with ->eh_timed_out hook.

This patch is against the current libata #upstream[1] + scsi-misc
#master[2]. I simply pulled scsi-misc #master into libata #upstream
(no conflicts) and made on top of it. Minimally tested on my machine
and seems to work fine.
