Device tree compatible match order bug fix
This branch contains a bug fix for the way devicetree code identifies
the type of device. Device drivers can contain a list of of_device_ids,
but it more than one entry will match, then the device driver may choose
the wrong one. Commit 105353145e, "match each node compatible against
all given matches first", was queued for v3.14 but ended up causing
other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs.
Merely reverting the fix and waiting until v3.15 isn't a good option
because there is code in v3.14 that depends on the revised behaviour to
boot.
This branch should finally fixes the problem correctly. This time
instead of just hoping that the patch is correct, this branch also adds
new testcases that validate the behaviour.
The changes in this branch are larger than I would like for a -rc pull,
but moving the test case data out of out of arch/arm so that it could be
validated on other architectures was important.
