Since commit 9484f2cb8332 ("clk: samsung: exynos-clkout: convert to
module driver") this driver is instantiated as MFD-cell (matched by
platform device name) not as a real platform device created by OF code.
Remove then of_match_table and change related MODULE_DEVICE_TABLE to
simple MODULE_ALIAS to avoid further confusion.

v3:
- Use '#define DRV_NAME' based alias. I see no point bloating the driver
with another platform device IDs array, as I don't expect this driver to
be used with any other platform device ID. Driver variants are already
selected based on the parent PMU device compatible.

v2:
- added MODULE_ALIAS

Sure, I'm fine with this either way. Thanks for following up!
