Subject: [PATCH 17/18] ide: allow device drivers to specify per-device type /proc settings
Turn ide_driver_t's 'proc' field into ->proc_entries method
(and also 'settings' field into ->proc_devsets method). Then
update all device drivers accordingly.
There should be no functional changes caused by this patch.
