tplink-safeloader: add support for TP-Link CPE510 v3.20

This adds new strings for the v3.20 to the support list of the
already supported TP-Link CPE510 v3.

The underlying hardware appears to be the same, similar to the
situation with CPE210 v3.20 in 4a2380a1e778 ("tplink-safeloader:
expand support list for TP-Link CPE210 v3")
