[U-Boot] [PATCH v5 03/10] rockchip: video: vop: Fix rk_display_init() return error

[Eric Gao]

It's caused by the difference of clk_set_rate function implement between
rk3288 andd rk3399.

clk_set_rate() of rk3288 return 0 in normal condition.
clk_set_rate() of rk3399 return input parameter in normal condition.

So modify clk_set_rate's return value of rk3399 in keeping with rk3288.
