personally I'd get rid of the num_clks as this value is static
instead I would add a #define with the number of clocks and then...

... use something like:
struct clk_bulk_data                            clks[MESON8B_USB2_PHY_NUM_CLKS];

clock -> clocks

by using a fixed-size array as suggested above you don't need to
dynamically allocate memory anymore
