mtd: rawnand: prepare the removal of the ONFI parameter page
The NAND chip parameter page is statically allocated within the nand_chip structure, which reserves a lot of space. Even not ONFI nor JEDEC chips have it embedded. Also, only a few parameters are actually read from the parameter page after the detection. ONFI-related parameters that will be used outside from the identification function are stored in a separate onfi_parameters structure embedded in nand_parameters, this small structure that already hold generic parameters. For now, the onfi_parameters structure is allocated statically. However, after some deep rework in the NAND framework, it will be possible to do dynamic allocations from the NAND identification phase, and this strcuture will then be dynamically allocated when needed.
