Latitude 5X10, please put "5510" instead.

@dell-client-linux Much like a previous related issue with using just "generic placeholders" (https://github.com/fwupd/firmware-dell/issues/91), please remove the generic "5X10" and use the actual laptop model number since:

1. You are not able to actually "search" for a Dell Latitude 5110 and find it!
2. There is only the 5510 possible and not a "5X10" as the latitude 5310 already has its own page (https://fwupd.org/lvfs/devices/com.dell.uefi59e05c3f.firmware).

Please do not put generic placeholders only. Specify the specific ones, also.
