Mux clocks are now described with a customized ccu_mux structure
consisting of ccu_internal and ccu_common substructures, and registered
later with devm_clk_hw_register_mux_parent_data_table(). As this helper
always allocates a new clk_hw structure, it's extremely hard to use mux
clocks as parents statically by clk_hw pointers, since CCF has no
knowledge about the clk_hw structure embedded in ccu_mux.
This scheme already causes issues for clock c910, which takes a mux
clock, c910-i0, as a possible parent. With mainline U-Boot that
reparents c910 to c910-i0 at boottime, c910 is considered as an orphan
by CCF.
This patch refactors handling of mux clocks, embeds a clk_mux structure
in ccu_mux directly. Instead of calling devm_clk_hw_register_mux_*(),
we could register mux clocks on our own without allocating any new
clk_hw pointer, fixing c910 clock's issue.
