Use platform_device_probe() instead of platform_create_bundle() when
compiled with DT support, since the latter function is not suitable for
handling the OF device tree.

The order of initialization is changed, since i8042_platform_init() for DT
requires initialized platform_device structure. To avoid searching of the
compatible node twice, the platform_device structure pointer must be passed
to the i8042_platform_init() function right after initialization by
platform_device_probe().

This is remaining weak place in the patch set. No ideas yet on
how to reduce the using of ifdefs to make code cleaner, need more discussion.
