VT6410 and SiS965 support,
+ few trivial cleanups as a bonus.

Please pull from:

master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/

to obtain following changes:

Aurelien Jarno:
sis5513: enable ATA133 for the SiS965 southbridge

Bartlomiej Zolnierkiewicz:
ide: remove duplicate documentation for ide_do_drive_cmd()
ide: remove unused ide_action_t:ide_next
ide: remove dead DEBUG_TASKFILE code
ide: remove dead code from flagged_taskfile()
ide: add missing __init tags to device drivers

Mathias Kretschmer:
via82cxxx: add VIA VT6410 IDE support
