[U-Boot] [PATCH v2 8/8] rockchip: video: vop: Fix rk_display_init() return error

[Eric Gao]

The function clk_set_rate() will return it's input parameter, so it's return
value in normal condition is nonzero. In this case, we should report an error
when it return zero rather than return a nonzero value.
