mtd: rawnand: Retrieve NV-DDR timing modes from the ONFI parameter page
When parsing the ONFI parameter page, save the available NV-DDR timing modes in the core's dynamic ONFI structure. Once available to the rest of the core out of the ONFI driver, these values will then be used to derive the best timing mode.
