clk: samsung: Revert "clk: Use device_get_match_data()"

device_get_match_data() function should not be used on the device other
than the one matched to the given driver, because it always returns the
match_data of the matched driver. In case of exynos-clkout driver, the
original code matches the OF IDs on the PARENT device, so replacing it
with of_device_get_match_data() broke the driver.

This has been already pointed once in commit 2bc5febd05ab ("clk: samsung:
Revert "clk: samsung: exynos-clkout: Use of_device_get_match_data()"").
To avoid further confusion, add a comment about this special case, which
requires direct of_match_device() call to pass custom IDs array.

This partially reverts commit 409c39ec92a35e3708f5b5798c78eae78512cd71.
