Kunihiko Hayashi 3b67e62130 dt-bindings: reset: Fix node descriptions in uniphier-reset example
Prior to adding dt-bindings for SoC-dependent controllers, rename the
reset nodes to the generic names in the example.

And drop redundant examples and a parent node of the reset as it is not
directly necessary.

title: Socionext UniPhier peripheral core reset in glue layer
description: |
Some peripheral core reset belongs to its own glue layer. Before using
this core reset, it is necessary to control the clocks and resets to
enable this layer. These clocks and resets should be described in each
property.
