Revert "ide: change master/slave IDENTIFY order"

This reverts commit b140b99c

.

[ conflict in drivers/ide/ide-probe.c fixed manually ]

It turned out that probing order change causes problems for some drives:

	http://bugzilla.kernel.org/show_bug.cgi?id=10239

Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now.  As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.
