[PATCH v3 2/6] clk: sunxi: move "ahb_sdram" to protected clock list

From: Chen-Yu Tsai
Date: Tue Jun 24 2014 - 06:00:30 EST


With sunxi_gates clocks registered with clkdev, we can use the
protected clocks list to enable the "ahb_sdram" clock, instead
of looking for it and adding CLK_IGNORE_UNUSED inline in the
clock setup code.
