clk: uniphier: add NAND 200MHz clock

Browse Source 
The Denali NAND controller IP needs three clocks:

 - clk: controller core clock

 - clk_x: bus interface clock

 - ecc_clk: clock at which ECC circuitry is run

Currently, only the first one (50MHz) is provided.  The rest of the
two clock ports must be connected to the 200MHz clock line.  Add this.
