sconfig: Ensure at least one `device` node below each `chip`

Even though `device` entries are children of `chip` entries in the
devicetree source format, the chips in the translated C structures
are only hooked up to device nodes. Hence, any chip with all its
settings will be silently dropped by sconfig if there is no device
node below it.

Let's adapt the parser to ensure that there is at least one `device`
entry. The intermediate `chipchildren_dev` rule applies until the
first `device` entry is found, then everything continues as before
with the `chipchildren` rule.
