Thibaut VARENE e1f3cf7ede ar71xx: mikrotik: prepend "RouterBOARD" to machine name for NOR devices 
When the device name doesn't already contain "RouterBOARD", this patch adds
this string to the machine name.

Most NOR devices already have "RouterBOARD" in their hardware-stored device name,
but not all of them.

This patch also makes the code more robust against buffer overflows.

* MikroTik SPI-NOR RouterBOARDs support
*
* - MikroTik RouterBOARD mAP L-2nD
* - MikroTik RouterBOARD 941L-2nD
* - MikroTik RouterBOARD 951Ui-2nD
* - MikroTik RouterBOARD 750UP r2
* - MikroTik RouterBOARD 750 r2
* - MikroTik RouterBOARD LHG 5nD
*
* Preliminary support for the following hardware
* - MikroTik RouterBOARD wAP2nD
* - MikroTik RouterBOARD cAP2nD
* - MikroTik RouterBOARD mAP2nD
* Furthermore, the cAP lite (cAPL2nD) appears to feature the exact same
* hardware as the mAP L-2nD. It is unknown if they share the same board
* identifier.
