firmware: arm_scmi: quirk: Improve quirk range parsing

Browse source

When a range contains only an end ("-X"), the number string is parsed
twice, as both "sep == first" and "sep != last" are true.  Fix this by
dropping the superfluous number parsing for "sep == first".

This does have a harmless functional impact for the unbounded range:
"-" is now accepted, while it was rejected before.
