Clayton Craft ad560591e1 deviceinfo: parse only required variables
This greatly reduces the chance accidentally adding dependencies to the
other (currently unused) variables later on. Getting away from depending
on deviceinfo has a lot of benefits, but mainly it helps offload
device-specific boot configuration to boot-deploy. Handling those
complexities in a shell script is often nicer.

Also, reducing the need to handle variables that contain lists means
that this app doesn't have to worry about how to merge/handle multiple
versions of those. That might be useful later if mkinitfs has to read
deviceinfo config from multiple deviceinfo files.

For example, trying to figure out how to merge these two things is...
ehhh...
        a_modules_initfs="abc bar banana bazz"
        b_modules_initfs="foo bar bazz bar2 guava"
