By this patch we still recognise the old binding ti,swap-xy in parallel to
the common binding touchscreen-swapped-x-y. This keeps compatibility
to older (out-of-tree) device tree binaries.
We do this in a separate patch so that it can be easily reverted in the
future to retire the old API. A notice is printed to remind developers
of using old API.
We also fix the bindings name for all in-tree device tree sources in
a separate patch.
