mtd: rawnand: Propagate error and simplify ternary operators for brcmstb_nand_wait_for_completion()
As bcmnand_ctrl_poll_status() return negative errno, so return true if
sts < 0. The < 0 case does not exist for wait_for_completion_timeout(),
so return true if sts = 0 and zero otherwise. Both of the true return
of them can be considered as a -ETIMEDOUT err, so return -ETIMEDOUT
if err is true to propagate err from its caller.

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.

mtd: rawnand: brcmnand: fix OOB R/W with Hamming ECC
Hamming ECC doesn't cover the OOB data, so reading or writing OOB shall
always be done without ECC enabled.
This is a problem when adding JFFS2 cleanmarkers to erased blocks. If JFFS2
clenmarkers are added to the OOB with ECC enabled, OOB bytes will be changed
from ff ff ff to 00 00 00, reporting incorrect ECC errors.
