When I started looking into the intel_cht_int33fe driver for an example of use
software node API, I have noticed that it's hard to get and code a bit messy.
Here is a clean up, main part of which is to introduce node groups and API to
register and unregister them. This and some pre-existing APIs can be used in
the driver.

So, because of cross-subsystem nature of this series, I may recommend to create
myself the immutable branch which can be pulled to Rafael's and Greg's trees
respectively. I'm also open for other proposals how to proceed.

  device property: export set_secondary_fwnode() to modules
  software node: Allow register and unregister software node groups
  platform/x86: intel_cht_int33fe: Convert software node array to group

  platform/x86: intel_cht_int33fe: Switch to use
    acpi_dev_hid_uid_match()

Some drivers when compiled as modules may need to set secondary firmware node.
Export set_secondary_fwnode() to make it possible without code duplication.

Sometimes it's more convenient to register a set of individual software nodes
grouped together. Add couple of functions for that.

Code looks and be read cleaner when software nodes are defined individually.
Convert software node array to a group in order to achieve above.

While here, switch struct initializers to C99 standard.

In one place we open coded set_secondary_fwnode().
Let's replace it with a helper.

The series looks good to me and I've also tested it on one of
the devices using the intel_cht_int33fe driver and everything seems
to work fine, so for the whole series:
