This patch adds support of MikroTik RouterBOARD 750Gr3, without the need
to reflashing the bootloader.
Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common
Since the image isn't compatible with RouterBOARD 750Gr3 installations
which have replaced the bootloader, the former used userspace boardname
is not added to the SUPPORTED_DEVICES, to prevent a brick while trying
to upgrade to the image with native support.
