clk: samsung: exynos-clkout: Remove misleading of_match_table/MODULE_DEVICE_TABLE

Since commit 9484f2cb ("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.
