apalis_imx6: revert fuse value set in mfgr_fuse
We have two commands to change the bootmode fuses: mfgr_fuse which set fuse 0/5 and 0/6 and updt_fuse which burns bit 4 of 0/5. Before BSP 2.6 we fused in mfgr_fuse 0x5062, which boots from the user partition of the eMMC. To workaround certain hangs we moved to fastboot mode and using the first bootpartition of the eMMC requiring a fuse value of 0x5072 which could be achieved by the then added updt_fuse command. At the same time the mfgr_fuse command was changed to also fuse 0x5072, revert that second change so that one can fuse both values, one with just mfgr_fuse and the later with mfgr_fuse;updt_fuse. Note that the mfgr_fuse command is only needed at module production time, a customer might need to use updt_fuse when upgrading an older module to be compatible with a newer image. The command is integrated into the image update scripts.
