slimbus: generate MODULE_ALIAS() from MODULE_DEVICE_TABLE()
Commit 9e663f4811c6 ("slimbus: core: add support to uevent") added the
MODALIAS=slim:* uevent variable, but modpost does not generate the
corresponding MODULE_ALIAS().
To support automatic module loading, slimbus drivers still need to
manually add MODULE_ALIAS("slim:<manf_id>:<prod_code>:*"), as seen in
sound/soc/codecs/wcd9335.c.
To automate this, make modpost generate the proper MODULE_ALIAS() from
MODULE_DEVICE_TABLE(slim, ).
