Revert "clk: sunxi-ng: sun6i-rtc: Add support for H6"

Browse Source 
This reverts commit 1738890a31.

Commit 1738890a31 ("clk: sunxi-ng: sun6i-rtc: Add support for H6")
breaks HDMI output on Tanix TX6 mini board. Exact reason isn't known,
but because that commit doesn't actually improve anything, let's just
revert it.
