nand_base: detect more ONFI flash
if the flash has a known type, the ONFI detection won't occur
and thus we may not detect the right parameters.
By testing both namd and pagesize, as done in the kernel, we
can detect ONFI flash with know IDs.
As an example on an i.MX53 board :
- without the patch :
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3
(Micron NAND 1GiB 3,3V 8-bit), page size: 4096, OOB size: 128
- with the patch :
ONFI flash detected ... ONFI param page 0 valid
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3
(Micron MT29F8G08ABACAWP), page size: 4096, OOB size: 224
in the first case the OOB size is wrong.
