Make some pointers of type intel_pmic_opregion_data as const as they
do not modify the fields of the structure they point too.
After this change, make the data field of intel_pmic_opregion
structure const as this data field is used for initializing the above pointers
that are now const.
Finally, make the struct intel_pmic_opregion_data * argument of the
function intel_pmic_install_opregion_handler as const as it is only
getting stored in the data field of the intel_pmic_opregion
structure which is now made const.
