John Crispin 9b2c7be0c4 ramips: important patch for HG255D
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.
