[PATCH] dt-bindings: rtc: ingenic,rtc: Use generic power-controller schema

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

From: Peng Fan <peng.fan@nxp.com>

Convert the binding to use the generic power-controller schema instead by
referencing power-controller.yaml and removing the local
`system-power-controller` property definition.

Acked-by: Paul Cercueil <paul@crapouillou.net>

V1:
 The power-controller.yaml has been merged in dt-schema, so
 resend this patch picked from link [1]. A-b tag is kept, since
 no changes.
