mtd: rawnand: get rid of the ONFI parameter page in nand_chip

Browse Source 
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.

Now that there is a small nand_parameters structure that hold all needed
ONFI parameters, remove the ONFI page from the nand_chip structure by
just allocating it during the identification phase and removing it right
after.
