[v3] media: ir-kbd-i2c: convert to i2c_new_dummy_device()
Commit Message
Convert this driver to use the new i2c_new_dummy_device() call and bail
out if the dummy device cannot be registered to make failure more
visible to the user.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Change since v2: move away from devm per Mauro's suggestion
Note: i2c_unregister_device() is NULL pointer aware so we can skip the
if in the last block.
