platform/x86: dell-wmi: use MODULE_DEVICE_TABLE() instead of MODULE_ALIAS()

WMI drivers can if they have specified an array of struct wmi_device_id
use the MODULE_DEVICE_TABLE() macro to automatically generate the
appropriate MODULE_ALIAS() output. Thus avoiding to keep both the array
of struct wmi_device_id and the MODULE_ALIAS() declaration(s) in sync.

Change driver to use MODULE_DEVICE_TABLE() instead of MODULE_ALIAS().
