docs: power: add it to to the main documentation index
The power docs are orphaned at the documentation body.
While it could likely be moved to be inside some guide, I'm opting to just
adding it to the main index.rst, removing the :orphan: and adding the SPDX
header.
The reason is similar to what it was done for other driver-specific
subsystems: the docs there contain a mix of Kernelspace, uAPI and
admin-guide. So, better to keep them on its own directory,
while the docs there are not properly classified.
