clk: amlogic: gxbb: drop non existing 32k clock parent

[ Upstream commit 7915d7d5407c026fa9343befb4d3343f7a345f97 ]

The 32k clock reference a parent 'cts_slow_oscin' with a fixme note saying
that this clock should be provided by AO controller.

The HW probably has this clock but it does not exist at the moment in
any controller implementation. Furthermore, referencing clock by the global
name should be avoided whenever possible.

There is no reason to keep this hack around, at least for now.
