clk: spacemit: k3: mark top_dclk as CLK_IS_CRITICAL
top_dclk is the DDR bus clock. If it is gated by clk_disable_unused,
all memory-mapped bus transactions cease to function, causing DMA
engines to hang and general system instability.

Mark it CLK_IS_CRITICAL so the CCF never gates it during the
unused clock sweep.
