brcm47xx: sysupgrade: fix device model detection

$(board_name) was providing content on "boardtype" (and optionally
"boardnum") NVRAM values. That function requires & expects more specific
and detailed model name extracted from the /proc/cpuinfo.

Fixes: f12a32630ff5 ("treewide: use the generic board_name function")
