[PATCH 7/8] gen_nodes: fix YAML indentation in pcipassthrough template

[Luis Chamberlain <mcgrof@kernel.org>]

The template was generating malformed YAML with improper indentation
and missing newlines between passthrough entries. This caused parsing
errors: "Colons in unquoted values must be followed by a non-space
character."

Fixed by:
- Removing the trailing whitespace stripping after 'pcipassthrough:'
- Ensuring proper indentation for all passthrough entries
- Maintaining consistent whitespace control throughout the macro

The generated YAML now correctly produces a single 'pcipassthrough'
key with properly indented sub-entries for all devices.
