[PATCH] arm: dts: socfpga: denali needs nand_x_clk too

The denali NAND flash controller needs at least two clocks to operate,
nand_clk and nand_x_clk.
Since 1bb88666775e ("mtd: nand: denali: handle timing parameters by
setup_data_interface()") nand_x_clk is used to derive timing settings.

Strictly speaking denali needs a ecc_clk too, but AFAIK such a clock
is not present on this SoC.
But my SoCFPGA knowledge is very limited.

Thanks,
