[PATCH 02/07] aic79xx: use tcq functions

[Hannes Reinecke <hare@suse.de>]

[-- Attachment #1: Type: text/plain, Size: 466 bytes --]

This patch converts aic79xx to use the midlayer-supplied tcq
functions.

We also set the queuedepth to '1' if tcq is disabled; the
aic79xx driver gets confused otherwise. Will set it back to
'2' once I figure out how to queue requests in the driver.
