Inside function set_chip_clock(), struct pll is supposed to be
initialized in sm750_calc_pll_value(), if condition
"diff < mini_diff" in sm750_calc_pll_value() cannot be fulfilled,
then some field of pll will not be initialized but used in
function sm750_format_pll_reg(), which is potentially unsafe.
