updated the guide, changed the ICX7xxx upgrade instructions slightly so a new/known uboot version is flashed first - this avoids the cases where switches coming with ancient 8030 bootloaders would error with "Wrong image format for bootm command" when trying to flash 8090m
also changed the "reset" instruction when coming out of uboot to "boot_primary" instead - even though a factory reset/default has been issued, configs don't get wiped until the OS fully boots. So if a user gets a switch where the previous owner had set/configured the switch to boot from the secondary OS slot, when following the guide and issuing factory set default and all the updates, then issued "reset", it would boot into the old #2 OS slot running god knows what. specifically requesting a "boot_primary" out of u-boot avoids that. thanks foot-gloves on github for the pull request
