clk: amlogic: g12b: fix cluster A parent data

[ Upstream commit 8995f8f1 ]

Several clocks used by both g12a and g12b use the g12a cpu A clock hw
pointer as clock parent. This is incorrect on g12b since the parents of
cluster A cpu clock are different. Also the hw clock provided as parent to
these children is not even registered clock on g12b.

Fix the problem by reverting to the global namespace and let CCF pick
the appropriate, as it is already done for other clocks, such as
cpu_clk_trace_div.
