For some domains the resets of the devices in the domain are not
automatically triggered. Add an optional resets property to allow
the GPC driver to trigger those resets explicitly.

Rob has approved this if it includes a proper explanation on why the
resets are not defined. See:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/20201105174434.1817539-9-l.stach@xxxxxxxxxxxxxx/#24147743.
Can you add an explanation to the bindings in the next version?
