mtd: rawnand: brcmnand: Fix mtd oobsize
brcmnand controller can only access the flash spare area up to certain
bytes based on the ECC level. It can be less than the actual flash spare
area size. For example, for many NAND chip supporting ECC BCH-8, it has
226 bytes spare area. But controller can only uses 218 bytes. So brcmand
driver overrides the mtd oobsize with the controller's accessible spare
area size. When the nand base driver utilizes the nand_device object, it
resets the oobsize back to the actual flash spare aprea size from
nand_memory_organization structure and controller may not able to access
all the oob area as mtd advises.
This change fixes the issue by overriding the oobsize in the
nand_memory_organization structure to the controller's accessible spare
area size.
