Removed legacy writes to ORT/PIT registers from
i40e_GLQF_reg_init(struct i40e_hw *hw) function.
Latest NVM versions contain all relevant values
and these values should not be overwritten by SW to
maintain driver/firmware compatibility and to avoid
conflicts with dynamic device personalization profiles.
