Subject: [PATCH v4 3/3] clk: amlogic: s4: remove unused data

Following the removal of the clk_regmap clock table from the s4-peripherals
clock controller driver, it appears some clocks are unused, which means
these are not exported or even registered.

In all likelihood, these clocks have not been tested. Remove the unused
clocks for now. These can added back later when they have been properly
tested.
