So far, the tool only supports stating whether an option is enabled,
disabled, or have a neutral 'allowed' policy.

But there's nothing stopping us from supporting something like:

- name: CONFIG_PANIC_TIMEOUT
  expected: int
  expected_value: 10

- name: CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE
  expected: hex
  expected_value: 0x1

- name: CONFIG_NLS_DEFAULT
  expected: string
  expected_value: "utf-8"

In v2 of this series, I'll make the schema explicitly versioned.  This way,
new features like the above can be cleanly added.

P.S.,  I can definitely implement such support, but I'm a bit hesitant to
adding features that are not yet needed by the existing mainline policies.

Thanks!
