r37505 add support for Huawei HG255D, but it only tested under a community
hacked u-boot ("lintel u-boot"), which has a different mtd layout compared to
origin one. If you install it on a box with origin u-boot, the origin factory
part will be destroyed, and your wifi interface will never up!!!
This patch shrink firmware part in mtd layout to exclude origin factory part,
and I will prepare another patch to fix the eeprom extract issue for box with
origin u-boot.
