Description:

As release at 2.8.2 (https://github.com/networkupstools/nut/blob/v2.8.2/drivers/Makefile.am#L60), nut driver sms_ser is now supported but missing from openwrt package list due to OpenWRT version at 2.8.1.

Probably may just repeat 82f36e0 commit with a change to https://github.com/openwrt/packages/blob/openwrt-24.10/net/nut/Makefile#L405 with sms_ser added to list of serial drivers.

If needed, I can try a PR, but I do not have skills with OpenWRT packaging and compiling, so it may need to be tested.

would also need to add it further down to be selectable; more similar to f5c0f82 but adding rather than removing drivers
