Move i8042_platform_init() call from i8042_init() to i8042_probe() to
pass the platform_device structure pointer, since the former function
now requires this argument.

Use platform_create_bundle() when there is no DT support in the kernel,
and platform_driver_probe() otherwise, which does not create a device.
