disp: msm: dsi: call pll set rate directly instead of a function pointer cb

The clock framework nulls the clock hardware init data, after a variant
of clk_register is called on the clk_hw pointer. This results in a null
pointer dereference when we try to call set rate in the PLL prepare
function. The call can be a direct call to the function rather than
trying to access through the init_data pointer of the clk_hw.
